To make a mini crib sheet (38"x24"x6" deep) you'll need (if yours is a different size, scroll down for how to get the measurements you need):
1.5 yd fabric
matching thread
54" of 1/4" elastic
Directions:
1. Wash and dry your fabrics. I used flannel for this one but plan to make a new that are just cotton.
2. Cut your fabric to be 38"x52"
3. Fold over into 4's so that the open corners are all together.
8. At this point, if you want to, you can zig zag or serge all the way around to give a nice finished edge. I don't have a serger and really didn't want to take the time to zig zag. We'll see how well these sheets wash and if they fray.
11. Stitch a casing using 1/2" seam allowance. I used my quilting thingie (I know it's got a proper name but I don't know it) to get a consistent 1/2". Don't forget to leave a space to thread the elastic. I like to do this at the beginning so I don't forget down the line.
14. Sew the opening shut and stand back to admire your brand new sheet. :)
Note: this is for MY specific mattress. If your mattress is a different size you're going to have to adjust the measurements. See below.
Here's how I did it.
1.I took the length of my fabric and subtracted the length of my mattress, then subtracted the depth of my mattress x 2, then subtracted the seam allowance x 2.
2. I then took the width of my fabric and subtracted the width of the mattress, then subtracted the depth of my mattress x 2, then subtracted the same seam allowance x 2 from step 1.
3. You want to make sure that you have the same size on each piece to cut out so you may have to do a little "wiggle room" math and trim it down a bit to get it figured out
4. To figure out the square you need to remove, add the depth of the fabric and 1 of the seam allowances. If you use the seam allowance x 2 you will have too small of a sheet. Again, experience here.
So, for mine-
mattress length is 38", 38+6+6+1+1=52" which is the length of fabric I started with
mattress width is 24", 24+6+6+1+1= 38" which is the width of fabric I started with
mattress depth is 6", 6+1=7" which is the side length of the square I removed.
