Some of you may know that I'm going to starting modding and casting puzzle soon. However, I don't know how to cut stickers. I am going to order Cubesmith vinyl sheets if everything goes to plan but want to ask skilled puzzle makers about stickering puzzles.
*Please do not suggest Dr.Sticker, I can't afford to get stickers cut at the moment.*
I am going to use a Cubesmith blade to remove stickers but to remove residue rubbing alcohol/white spirit have been suggested. How do you use these to remove residue (technique)?
How do you cut custom stickers? I am assuming that it requires measuring the pieces but am not sure how to cut the stickers.
I would appreciate some help with this.
Thanks to everyone who helps.
