For a while I've wanted to make a synthetic quilt, after seeing other peoples quilts and how they used them in conjunction with down I wanted to give it a go. Before spending ££ on nice top fabrics, I've made a prototype today using the fabric from @Gadget via the pay it forward thread. Apex, grosgrain and locks from https://www.adventurexpert.com and other bits I had laying around. The Box of Goodies Cut to size, 220cm, 140cm across the top, 120cm across the bottom. The finished quilt. 50cm zip with shock cord draw sting in a separate channel top and bottom. Cord locks and loops, one just above the zip, another 50cm up form that and another 50cm up 310g with the extra shock cord that weighs 4g so the total quilt weight is 306g. With a stuff sack it should be around 325g. Clip and draw cord at the top of the quilt.
