As promised, the very first WhatTheCraft video tutorial is here!
Check it out for step by step instructions for making a square bottom bag.
And while you’re at it, go subscribe to my YouTube channel! There are lots more tutorials to come (including applique, inserting snaps, and t-shirt collars)!
Lots of people ask about making different sized bags. Here are a few sizes to use as guides, but you can of course make a bag of any size with this tutorial.

Remember, these are guides only! If you want to try a different size, I’d suggest making a paper pattern first. That way, you can fold up the gusset and get a better feeling for what the bag size will be like when it’s completed.
