This is a custom stamp for a game I am completing. Again, I had a quote for printed cotton bags (I need 250 of them!), and realised that although it would take some more time, it would be cheaper, and look more aesthetically pleasing, if I made and stamped them myself.
The stamp itself is 100 by 70mm, and took 54 minutes to cut (Speed 220, Power 65), using rubber stamp material from Amazon (this red one here: https://amzn.to/3RhxNT2), so excluding ink and printing costs, it cost about £2 to make.
EDIT: To make the stamp, I was advised to use Pathfinder > Exclude, which I’ll definitely put into play next stamp!
You can go straight from Illustrator to the Glowforge and click the stamp maker button to invert it.
Inverting it in Illustrator would be something like… combine everything into one path, draw a big rectangle, put the design over the rectangle, and “minus front” or “subtract” or whatever Illustrator calls that function.
I stamped 150 bags for a small convention, and it took ffffooooorrrreeeevvvveeerrrr!
