Things You'll Need:

- Thin elastic
- Straight pins
- 2 safety pins
-
Step 1
Measure your crib mattress. The standard crib mattress is 27 1/2 by 54 1/2 inches, but they are all different depths. You need to measure the length plus the two sides, plus 3 inches. Then measure the width, plus the two sides, plus 3 inches. Cut the fabric to your measurements.
-
Step 2
To fit the sheet, place the fabric on the mattress and fold the sides to make corners. Pin in place and then sew the folds on the sewing machine, right sides of the material together, sewing on the wrong side. If you can not sew, skip this step.
-
Step 3
Fold over the raw edge about 1/4 inch and then again 1/2 inch. Sew the hem, all the way around the raw edge, leaving the last inch open. If you can't sew, iron the hem in with hem tape, but make sure to leave a sleeve in the hem.
-
Step 4
Feed a thin piece of elastic about 80 inches long through the hem by attaching it to a safety pin and working it through a little at a time. Attach the other end of the elastic to the opening with a second safety pin to hold it in place.
-
Step 5
When you get the first end of elastic through the hem, hold the two ends together and remove the safety pins. Sew the two ends of the elastic together. Sew the inch of open hem closed. Your sheet is finished.
