On last nights to do list: warmer crib sheets for Youngest. Crib sheets really are a simple thing to make. It's pretty much cutting out a large rectangle from the fabric of your choice, cutting 9 in. squares from the corners, a little sewing, a little heming, a little elastic and presto! Crib sheets! Ok, so that wasn't a great tutorial. Here's a better one at make-baby-stuff.com
Here's an example of what your corners should look like after they've been sewn (but before finishing the edges and adding the elastic).
And this is the finished product!
All told it only takes about an hour and half. So get over to the tutorial, then head for that sewing machine and have at it!
