Gap Cover

 Cardboard pattern created by trial and error fitting.  Rotary fabric cutter made the job of cutting out the pieces easy.

 Pre-creasing seams prior to sewing made holding a straight line much easier.

 Marking the hem line prior to setting the crease using an iron.

 The finished pre-creased panels ready for Velcro and zipper

Sewing on the fuzzy side of the Velcro to the outboard edge of the gap panel.  Notice the zipper already sewn to the center edge of this panel.

The advantage to this approach makes it possible to easily disassemble the glider and also adjust the fabric tension to get a really nice smooth gap cover.

I will add a photo of the installed cover soon.
