I managed to make a thing! It feels good to finish something.
Pattern: Just Hatched Baby Leggings by Rae Hoekstra of Made by Rae
I made these out of an old polo shirt of my husband's, so they aren't a super fun exciting print. Rae suggests using old tshirts for the fabric, and this is brilliant because if you line it up correctly you don't have to hem the bottoms. Win! They took me several naptimes to complete, though they would be a quick project if you have half an hour of uninterrupted time. The elastic casing is a bit wonky due to rushing and also not being super experienced at sewing knits. I've bought a few large stretchy tops from a charity shop to make a few more pairs, since stretchy trousers / leggings are turning out to be super useful for us. You can see they fit over his giant cloth nappy, which is awesome. I am going to try to adapt the pattern to make them a bit bigger so he'll have some to grow into.
