These are a simple pattern with an elastic waistband. There is a lot of room for creativity because they are reversible. I went with a basic lightweight grey corduroy for one side, but couldn't resist a bold wacky flannel print for the other.
The gears and bolts in the pattern made me think of wheels (both our boys will spin the wheels on strollers and other toys), but Patrick immediately thought of his dad's cycling interest and helped design and make a onesie to complete the outfit.
Patrick screen-printed one large gear and I appliqued three small ones from the flannel fabric to look like a bicycle.
An embroidered chain completed the look. I'm pleased with how it turned out, but not entirely confident it will hold up very long on a playful toddler. Maybe he'll outgrow it before that's an issue.
