I already posted this in a thread in the toy forum but I thought I'd post it here too.
How to make stickers with paper, duct tape, and glue.
Out of necessity, one day i sat down with a bunch of craft stuff and experimented until I created a home made sticker.
Step 1. The backing.
To create the backing you take a piece of paper that you don't plan to use any more and you cover it in duct tape or an equally smooth tape. I use some shitty "clear" duct tape I got at big lots because it's not actually clear(and therefore useless), the smooth side can have duct tape ripped off it without paper staying on the tape, and because it can usually hold onto the backing instead of going with the duct tape. These are things you should look for in an alternative tape if you want to save your duct tape for better things.
Step 2. The sticky part.
This is the part of the sticker that will actually be applied to the surface that you stick your sticker on. Take the duct tape and apply it in a different direction than the tape on the backing. Be very careful with the tape, if you accidentally get it dirty, don't rip it off whatever you stuck it on then use it for the sticker. If it isn't clean it wont stick, that's why the backing is coated in tape. Make sure to keep the tape smooth so that the paper stays on better. Sometimes the tape can be hard to remove from the backing so what Ill usually do is take some scrap tape and stick it in the corner between the backing and second layer of duct tape. This creates a pull tab for quick removal. If your scrap tape is too thin you can sometimes pull it and just rip a strip between your sticker and backing.
Step 3. The image.
Now all that's left is the part that you want people to see. I recommend creating your image beforehand so that if you make a mistake you don't lose an entire sticker.
Simply take your image and glue it to the backing. Be sure to use less glue towards the middle and use more glue on the edges. If you use too much glue it will fuck with the image. After you put the paper on the glue(or the backing on the glue) squeeze out as much glue as you can by running an old credit card or a piece of cardboard over it. The corners have a tenancy to be what causes the paper to peel so what I've tried recently is not gluing the corners with regular glue then after it dries finish up the corners with super glue. I haven't been doing this last part long enough to see how they last but I think it's gonna stay up longer.
I've used this to create stickers from printed pictures without any sticker paper. Sticker paper is easier but I don't have any so I created this, plus I suspect duct tape stays up longer than what they use for glue.
