My daughter is in the middle of swimming lessons now and her other suit was looking too small, so I made her a new one last week. Kwik Sew 2605 worked well for me the last time, so I used it again, this time making the two-piece version (so much easier for bathroom breaks).
I cut a size five and the only change I made was to take it in ½” on each side of the bottom.
The racer-back is as nice as I thought it would be - no straps falling off the shoulders. I considered using a double needle for the hems, but went with the triple zigzag instead.
Sewing this suit felt pretty putzy while I was doing it - quartering all the elastics and suit openings, getting it all lined up, serging the elastic on, etc. But, really, it didn’t take very long. It was faster than shopping for a suit, I’m sure.
There are no less than 14 things I would still like to sew for summer. There isn’t that much summer left and I’m working on some window treatments again now. Soon I’m going to have to decide if I want to sew for summer to the very end, or hang it up and get started on fall. Tough call.
