Measure the length and width of your pillow.
The length of your fabric should be:
2 x length of pillow+seam allowance+ overlap(probably about 3-4 inches.)
The width of your fabric should be:
width of pillow+seam allowance
If you have a 16 by 16 pillow insert, then your width and length should look like this:
Then cut your fabric.(Easy enough, right?)
