I found this tutorial based off the Pottery Barn ones a few months ago: ValentineChairBackers.
Just had to make them, I thought they'd be super sweet at the girls' little table. I also am in love with sewing bags and such.
I even learned how to make a button hole on my machine! I think they turned out stupid cute. I made my own covered buttons as well, which is very fun. One fell apart, but I'll get it fixed. I think I'll let the girls play with them for awhile, then it will be a fun tradition every Valentine's Day. I save up any cards they get in the mail and put them in here so they can open all at once.
