(JH) Hands-down this is the best crib skirt tutorial I have found on the web. A little bit of sewing, some velcro pieces and anyone can make this. I made Maddie's based off these instructions (except for the little insert piece...I have decided to forgo that to keep the look really clean and simple) and they worked very, very well.
Crib Skirt Sewing Pattern--I'm not usually one for bed skirts at all, but...you never know *shrug* I like that this has a clean and simple design that can be used with any fabric choice. Also, it would probably be easy to adapt to any size bed by just adjusting the measurements (should I become a bedskirt-lover after all)
