The bottoms are so easy - I used New Look #6847 for Bean's pants and Burda #9772 for Sprout's. They're constructed exactly the same - the only difference is size. The tops were from Target - Cherokee girl's t-shirts (don't tell Bean, but the slim fitting girl's shirts are just so much more flattering than they boxy boy's shirts) that I appliqued.
Don't you love Bean's shirt? I used the Jolly Roger pattern that I got at Crap I've Made. When sewing with knits, even doing applique on a t-shirt, please don't forget to use a ball-point needle. I can't tell you how many shirts I've nearly shredded using a regular needle on knits.
They love their new jammies - it's a rare, rare day when I can get Bean to pose for me, so I know he's pleased. And now, some gratuitous photos of the kids, who were being totally cute today.
