I did my first big DIY project and finished a Climashield TQ made from 5oz Apex and 1.1oz ripstop. I sewed the perimeter leaving the bottom open with the fabric inside out and then turned it right side out. I then sewed the bottom closed with a GG channel for shock cord to cinch up.

How should I go about adding a ripstop channel at the top for a neck cinch and gg to the corners? I also have some omni tape I want to add 1.5 ft up the bottom to make a footbox. I should have planned all this out before I flipped it and sewed shut but what is the best way to make these additions at this point? Any expertise and guidance is appreciated. I was also thinking I could double duty the quilt for a full length UQ if a hiking buddy tries a hammock.
