Just a little something I made, great for keeping your pencils organised, when measuring the fabric on the width do 1 inch per pencil & go as wide as you want, then the height can be the length of your pencils plus 3 more inches that's on 2 pieces of the fabric on the short piece of fabric measure less than half on height & same for width.
Stitch the gross grain ribbon on the small piece of fabric before you join on the larger pieces & leave extra on side to help with when you roll up the case & tie off.
Hope I explained OK just e-mail me with any questions. firstname.lastname@example.org
