... like when I decide to come up with a pattern for a tote bag on my own, instead of first searching the internet for advice. Yes, a square bottom tote bag sounds incredibly easy, so I blithely sketched out a pattern.
Unfortunately, it turns out that sewing together a square corner with multiple pieces of fabric sucks. There's also the small problem of my complete lack of ability to mentally picture how large something is going to be. Turns out 18 wide x 15 tall x 8 deep is absolutely massive - more suited to a beach tote. Sigh. I showed the results to my mom and the first thing she said was "You should have done gussets," which meant nothing to me.
So I ended up doing what I should have done in the first place. I googled it, and found an amazing tutorial online (here!) that is about a million times simpler than my attempt.
Result - a perfect little bag to carry a change of clothes for when I go to the gym.
I lined it with some super soft pink material from some vintage sheets.
Lesson learned - other people are smarter than me and I should at least see what they have to say before I go haring off on my own.
