|We all know that babies shouldn’t have blankets in their cribs, but once kids get older, they often continue using a crib-sized mattress. So why is it that you just can’t seem to find flat sheets for those beds? Lucky for you and me, we can sew the things we cannot find. My son is almost 2-1/2 but is still content in his crib. It was time for a big-boy sheet. Also see our other posts on nurseries: 1, 2, 3, 4, 5.

|I’ll show you below how to determine yardage. Then you’ll need enough ribbon to span the width of your sheet. The ribbon is purely decorative and completely optional.|
|The average crib mattress measures 27″x53″.
I calculated my sheet size as follows. You can substitute for a larger mattress, but the mattress depth (thickness) will be larger. You can apply this tutorial for any size of mattress, although multiple widths of fabric may be needed for larger mattresses. You have 90″ of width for the sheeting fabrics and for some mattresses, that might just barely cut it for the length of the mattress, and then you could buy enough yardage to go across the width of the bed. In other words, you’d be rotating the fabric 90 degrees from how I’m demonstrating here.
