The 2 fitted sheets and the bumper are done. Hurray!!! It was a bit of a pain to cut the pieces out because in the move I lost my clear quilting ruler, which makes using the rotary cutter and mat more difficult especially with larger pieces.
This is my great idea to cope without the clear ruler. I used Andrew's laser level instead; it worked pretty well if I pulled the fabric up so I could see the line.

This is the underside of the completed fitted sheet.

The sheet on the mattress.

The sheet on the mattress in the crib.

The bumpers and the sheet on the mattress in the crib.

The inside of the crib with all the bedding on. It kind of looks like a pond.
Now all I have to do is make the ruffle. It will be easier to cut the pieces for this since I got a new quilting ruler and a larger (24" x 36") cutting mat; I love JoAnn's coupons.
