The leftover sleeves gave me enough fabric to make this baby romper. I made this using Simplicity 3508, which is a reprint from a 1950s pattern (I'm not sure if this is still available, but you could try your luck on eBay or Etsy). This will remain unworn for the foresee-able future as I don't know anybody who is pregnant nor small. Which is probably just as well because although this is tiny and cute, it's not perfect. I'm going to practise this one a bit more and make some changes. Especially to all those buttons. And buttonholes. Moan. Making buttonholes is like the worst thing ever.
I have another similar sized shirt in my stash and I'm thinking I might have another go. Maybe I could get two rompers out of the next one? I might try that on a day I'm feeling a bit clever, but not before I buy a new iron with a better attitude, I think.
