I started with a fitted crib sheet tutorial from Dana Made It . It is about as easy as any tutorial can be. She has a few pictures of her steps. I didn't take any pictures so if you're a visual person, like me, you'll want to check out her tutorial. Here's a breakdown of the steps and pics of my final products.
What you'll need:
2 yards of fabric
2 yards of 1/4" wide elastic
30-45 minutes of time
Take your sheet and fold it in half. Fold it in half again, making sure to line up your edges precisely. Cut an 8x8" square out of the top corner with all the lose edges. Next you want to make your pockets for the corners of the mattress. In each of the four corners you've cut out, line up the sides right sides together. Sew them together to form the pocket. Serge or zig zag stitch all the way around the edges to prevent fraying. To make the casing for the elastic, iron down the edge of the fabric about a 1/3" all the way around. Sew it down all the way around leaving a 2 inch opening to thread the elastic. Attach a safety pin on the end of the elastic and thread it through. Once you get to the end, zigzag stitch it multiple times along the end so it holds. Then close up the 2 inch opening. Shift the sheet evenly around the elastic and put your made to order sheets on your mattress!
First my first go at it, I couldn't be happier! I tell you what, if there ever comes a time when I need to decorate another nursery, this gal is making EVERYTHING!!! Why be limited by what's in the stores? Not me! Not anymore!
