wool shorts

I know some people don't care to knit in the summer, but I do. I suppose it's mostly out of necessity though. If I didn't knit in the summer I'd never get anything done and the baby needs wool. I had planned on making Oz four pairs of wool shorts for this summer season, but realized some wool from Carter would fit him and I made a pair out of a upcycled sweater so I think I'm only going to knit three pair. I'll also need to make a pair for my BFF's baby girl. This is the first completed pair:

These were knit with Three Irish Girls Lindon Merino in her Liam colorway. I knit them on 7's even though it's an aran weight yarn as I like the stitches to be tight when used for the purpose of keeping urine of my jeans.

I used a trim yarn to Huckleberry Knits' Flying Fish colorway (which is what's on the needles right now) as it happened to match the gray perfectly. I love when things work out that way. I also tried out a new crotch gusset. It's functional, but it doesn't look quite right. I used a k1f&b increase. Anyone know what I did wrong?
