Hallo ich zeige euch heute einen kleinen Teil meiner, in diesem Jahr entstandenen, selbstgezeichneten Stempel, die ich auf die Postkarten male 
.
Hello I show you today a small part of my, created this year, self-drawn stamps that I paint on the postcards 
Welcome to the Forum Dorit! Very cool & creative stamps - thanks for sharing them!
Wow! I absolutely love this. What a talent! The last one immediately made me laugh. I think you really make little bundles of joy 
Welcome to forum, these stamps are beautiful, keep drawing and creating more amazing stamps, keep sharing them in future ))
Wow, these are absolutely beautiful! I love when people get creative with their postcards. The one with the cat is my favourite 
Echt toll!
I agree! These are WONDERFUL!!! A compilation for the year would make a great postcard. Keeping following your creative spirit!
They are wonderful 
I’m not an artist, but I’m in love with colours, paper, patterns…
That goes well my love for Mail/ Mail Art - it’s good to have a place where to send the creative outputs, no need to store them
A while ago we did a crazy acquisition and bought a vintage perforator, so now I can perforate paper to make my own decorative stamps.
Most often used are those I use for writing the ID for official postcards, I will add a photo later.
I made these “RR-identification” ones a while ago using a text rubber stamp and brilliant pattern rubber stamps (and markers) for the background:
Here is my fake stamp postcard, here the holes are just fakes with black pen :
Oh wow! You have a vintage perforator ? How cool is that! 
Hello fellow Postcrossers,
Have you heard of ArtiStamps ? I had not heard of them until this year. Does anyone make them ? Or have you received ones created by others ?
I have never made them yet as I do not have any machine like a sewing machine or tools to perforate to make them look like postage stamps. But I have received some created by others on an art exchange site.
If you have Artistamps by you or other artists, please show us !
Here are some that I have received :
Also, I am wondering how the perforate machine for ArtiStamps look like ??
Our very old, vintage perforating machine looks like this:
I just opened a trade topic:

You can also buy stamp perforating mechanisms on Etsy, but you probably can’t perforate more than a couple of stamps at a time, let alone entire sheets.
In Japan, there are utility knifes made in Osaka by OLFA that are a round shape. It rolls and can perforate as in postage stamps. I was at the major stationery shop in Osaka yesterday and found a couple of such round utility knifes in different size but the smallest sized one that I was looking for was sold out. But I am going to get it sooner or later. It was about only 600 yen ( 4 Euro ) ! I will show it in this thread when I get it
Edited to add :
Well, I bought the round utility knife that I mentioned above but it turned out it cannot perforate as in postage stamps …
