Quite a while ago, I shared the underwear holder that I made for Firecracker. I finally got around to making one for Boy. I found this pair of newborn pants with attached suspenders a neighbor gave us a while ago.
I made it the same way by sewing the legs shut.
We keep Boy's underwear in the bathroom because we're still in the potty training phase and that's where they're most useful. The suspenders are perfect for making it hang inside the cupboard door.
I imagine you could easily accomplish the same thing with adding your own elastic, and you could even cover it, so it doesn't look so...um...odd...
I know...a little weird, but it took about 5 minutes and was pretty much free...and it works...and hopefully we won't need it too much longer...and Boy likes it.
