All the grommets are filed and the pieces are together.
There are channels right against the seam lines on all the pieces. When I sewed those channels I sewed the side next to the seam just inside the 3/8 seam allowance line, then when I sewed the seams connecting the pieces I put the needle just outside that outer channel.
I guess I could have just sewn the pieces together and then sewn those channels, but I didn't. Now the question is do I insert boning then tuck the threads away, or do I tuck them away before I slide the reed in? Maybe it doesn't make a difference, but I'm sure it does. Anyone with more experience know if it's preferable to do one before the other?
