You may know that running paper through your sewing machine with a standard needle creates enough of a perforation for tear sections of paper. But for a long time I have been wanting to create actual circle cut perforations, not just piercings, to similate actual postage stamp edges without having to punch holes one at a time with some kind of hand tool. Well, I dug around the internet enough and found an idea in a Q&A about making movie props. So I gave it a try and it works pretty good. Not perfect, but does create a more realistic postage stamp perforation than any other technique I’ve tried. 
I used my good sewing machine, but please use caution when trying this, I would hate for you to mess up your own machine with this project. If this is the type of thing you think you would like to do often for scrapbooking, collage, wedding invitations, etc, you may consider finding a really cheap used sewing machine, since it only has to move a needle up and down, even a machine that doesn’t work well may do.
I purchased brass tubing to replace the needle in my sewing machine. The tubing walls are too thick to cut through paper, so I used my little Dremel Stylus tool to grind down the outside area of the end of a piece of 1/16 x .014 brass tubing found at the hobby store. Larger tubing would not fit in my machine. (A bit more precision grinding would probably give the end a sharper edge for cutting cleaner, I may go back and work on that.)
I cut the tubing shorter than the length of my sewing machine needle so that it didn’t poke too far down into the bottom of the machine when stitching.
I created some stamp images for this tutorial using the vintage printer cuts I posted the other day, separating the images enough to perforate between. 
I placed a piece of card stock below my paper to get the tubing/needle to go all the way through the paper as cleanly as possible. I adjusted my stitch length to space the holes as I wanted them.
Once all perfs have been made, and card stock pulled away, you can either fold along perforations and tear stamps apart for a rougher look, or use an Xacto knife or scissors to slice down the center of the perforated holes for a cleaner look. 
If you will be doing lots of perforating, you may need to remove your perforating needle and poke a straight pin into it to remove any build-up of paper inside every now and then.
UPDATE: Thanks for all your comments regarding stamp perforation edge scissors-those do work well for individual stamp edging. And the rotary tools for creating perforation (dashed lines) for tearing away. But the beauty of the brass tube needle is that you can create hole perforation lines that do not run the edge of your paper, such as this save-the-date I’m working on for a friend.
Absolutely fantastic! Damn, you are clever!
Leave it to you to figure it out!!! I've used the biggest needle I have, but it's just not enough!!! Thanks for sharing this awesome technique!
Interesting technique. I always use a broken needle – missing the point on it. I like your idea though – bigger hole probably!
Such a great idea! Thanks
I just discovered your blog, I'm in awww of your fantastic ingenuity!!
Didn't even know that I would want to make my own perforations….now, I'm sure I need to!!
Just unbelievable great idea! So cool… Thanks so much for sharing. I got to try.
You never cease to amaze me! That is such a great idea.
Brilliant! I love the effect! And to think you come of with these ideas without the use of mind bending pharmaceuticals!
again- you have the most amazing brain! Being less creative, but still loving the effect of postage stamp edges, I bought a decorative edge scissors and simply cut my stamps out.
BRILLIANT!
You always amaze me, neat idea.
You are brilliant!
Great idea! There is a small paper cutter called a Cutterpede that has a little perforated cutter that does this for you. I have one and it works great, I got it at Michael's.
Greetings ..
Do you know if those Cutterpede gadgets are on sale in the UK? Could you post a pic of the finished results of perforating paper?
Thanks for your time

Cathe,
You are so clever! I love this..it really is realistic and I do have to agree with you on using an old machine for this..thanks so much for sharing this.
Have a lovely day,
Stephanie
Ingenious!What will think of next?!
Every time I check your blog you amaze me with yet another Bright Idea! I'm picturing a book in the future!
Maureen
I love visiting your blog and seeing such clever and fun ideas. Do you happen by chance to be a fan of Jo Mora?
I just love everything here, it feels like my own home. I know that sounds silly, but I'll say it anyhow.
VERY clever idea!!! Thanks so much for sharing it!!!
Fantastic!
Very clever! Now, do I try that technique tomorrow, or do I go ahead and clean the room the sewing machine is in like I was intending. Every time I read your blog, I think I need to try your ideas! You are one ambitious person!
I have to agree with Maureen…every time a check your blog, you have another brillant idea! Keeps me going.
ALWAYS inspiring!!
Holy Moly! This is an idea of such extreme genius, my head might explode!
You are ALWAYS full of such great ideas! Thanks, and keep them coming!
Wow – they look very cool. I have decorative edge scissors that do the "stamp" cut. I think I'll stick with those
How awesome is this?? Thank you!
Is anyone else terrified that Cathe will get on to us and her blog will suddenly disappear, to be replaced by a brilliantly bound, vintage covered book of more of her infinite creativity?
Thanks for your generosity, Cathe!
Ellen
You NEVER cease to amaze me!
Beyond awesome!
This is BRILLIANT! I loooove the Save the Date cards!!!
Oh, by the way – you should definitely submit this to Totally Tutorials!

I am now your faithful, loyal fan. This is AWSOME. Someone else cook the kids dinner, mommas got to get her craft on!
Gorgeous save the date. Are you printing in color and leaving the text white (no ink) or are these screenprinted? Thank you!

The first way : )
Thank you! This blog post will be advertised on CraftCrave in the Printables category today (look for timestamp: [16 Feb 01:00pm GMT]).
omg they are amazing!
i want to do
Wow, this looks amazing. I’m guessing hobby lobby has the 1/16 x .014 brass tubing? I can’t wait to use it on my daughters birthday party invitations next month.
Thank you so much

Love it! Agree with Kathy though that a broken needle is a slightly easier way to do it, although it doesn’t look as good as yours. Dave @ http:///www.red20.net
Thank-you for that bright idea. I’ve been wondering how I might afford an expensive perforating machine; the cheapest costing £130 .. far too much for a pensioner who only wants to perforate 100 home-made stamps to fit around the borders of a watercolour painting of a postman delivering mail. I’m now on the scrounge for a non-working manual sewing machine.
Your pics make things quite clear, but I’m wondering if I could buy half a dozen stamps from you to keep as examples of the standard I’ll be aiming at if I ever get up and running, or should I say perforating.
Cheers
Edward
Would you consider making 1 or 2 sheets on photo paper for me, say for $5 each and I pay shipping? I want to make custom stamps and gum is not a requirement but do you have a tip for that?
that is so clever…

Very interesting. I collect stamps and have wondering how to make fake stamps with pictures of friends, etc. (Just for the fun of it of course, not to use or to counterfeit, as is often done.) I was trying to print on the selvage which is the blank paper sometimes attatched to stamps on the borders of the sheet. I never thought of using a sewing machine. The next step would be adding gum. a simple formula should be easy to find and it could be rolled onto a sheet, probably before perforation as printers used to do before self-adhisive stamps.
Hi, Cathe.
Your technique may be of interest to mail artists who make “artistamps”. Most that I know of use old postal perforators and as one earlier comment states, they are expensive. Also, a search of tool and stock suppliers might turn up already sharpened stainless steel tubing.
And a question. I don’t see where you say how you hold the sharpened brass tube in the machine. Does it slip over the needle?
Y’r [new] ol’ Bud, Fike
The tube fits up into the shaft just like a needle and is tightened into place with the thumb screw. So you treat it just like a needle being replaced in your machine. If your not familiar with machine needles, they are much thicker at the base area than the tip.
Hope that helps. See link in text for the source that inspired me. It’s a prop makers site.
Dear Sir ,
We are a Trading Company in Bangladesh,one of our costumer need
