This does mean, though, that we have to say goodbye to some of our old favourites to make room for the new. And in the same way, I'm using up my retiring DSP to make room. I like to keep gift bags ready-made so that if I need one in a hurry they're good to go - and these bags are about as large as you can make from 12 x 12 inch paper.
The finished size is 8 x 8 x 4 inches, so they'll hold quite a bit.
Here's the how-to-do-it video.
You could easily vary the dimensions a bit if you wanted - how about 9x9x3 or 7x7x5? Why not give it a try?
Anyway, keep crafting!
