If you are not entering your quilt in a contest, the size you make your hanging sleeve will depend on the width of your hanging rod. Usually, cutting a strip of fabric six to ten inches wide will work. (Contests often specify how large the finished size this sleeve needs to be. If the contest specifies that the sleeve needs to be 4 inches, you would cut your fabric 9 inches wide. This is how you would do the figuring..double the size of the sleeve and add one inch. 4" X 2=8" + 1"=9").
I usually cut my sleeve 1/2" shorter than the finished width of the quilt. (If my quilt measures 12" wide and I want a 4" finished sleeve, I cut my fabric 9" (see above) X 11 1/2" (12" - 1/2"=11 1/2").
First, I measure the quilt.
1. Cut the fabric the width and length you have previously determined. (Again, if your quilt measures 12" wide and you are making a 4" finished sleeve, cut your sleeve fabric 9" wide (see above) by 11 1/2" long.)
I hope you find this tutorial to be of help to you when you are making a sleeve.
