Sewing is interesting. I make a lot of sewing mistakes and end up having to pick stitches out so I can redo. Normally this is not an issue but with swimsuits it's a total PIA. 1. I use a smallish zigag stitch so it will move with the stretch of the fabric, not break and not come out. and 2. The thread is really hard to see against the spandex. Plus, you are spending time with your errors, wallowing in the proof of your own imperfections.
While I was picking out stitches I felt so tired, my back ached, I swore I was going to just put this down and go do something else and come back to it another day. But I kept at it. Then, when I was doing sewing, in other words, moving forward on the project, I was all energized. No back ache, not tired, planning whether my first wear would be the green side or the print side.
Funny how the old brain works. I am grateful that it still does!
