It is true!
So, here is what I do. I save it up and trim it down (using my scrapbooking trimmer, scissors, craft punches, etc). I round the corners using a corner punch and punch holes using a hole punch.
Then let the kids write or trace a drawing on it. They shrink up thicker and heavier than the storebought film.
I also like to make teeny tiny ones & have the kids write their names and the year on them. I use them to tag certain xmas ornaments so we know whose are who’s. Plus seeing their penmanship is always cute! I use a jump ring to attach the nametag and it is small enough that it is unobtrusive.
And because I am often lame about taking photos as I craft here are some other photos to show the shrunken size.
