Luckily they're the cutest thing with two legs and they're still! huge on him, so I happily made him another pair today, un-flannel-lined, and with a butt-accentuating contrasting panel.
The main fabric is Echino cotton/linen blend and the butt panel is something out of print from my scrap stash.
Made from one of his Dada's old concert Tshirts, normal baby 5 is transformed into hip, too-cool-for-school, Beck-loving 5! Kind of.
These are made from a pattern I made myself.
