I am making a vinyl cushion (of sorts) that is 18" x 14" x 5.5"
I plan to install a zipper to remove/install the foam and i have some questions regarding zipper install.
Is the zipper install the same as for uholstery instructions in my handy dandy RD: complete sew guide ? or are there any special concerns ?
is there a better/best placement for zipper strength or ease of foam removal ?
I was considering putting the zipper on a long edge since there is already a seam there and then i would not need to make another seam just for the zipper on a side ? but i am not sure that is the best idea.
If i want a hidden zipper do i fold over the vinyl as with the more flexible fabrics ? that is making a basted seam and sew the zipper then remove the baste threads and top stitch ?
does anyone have some helpful ideas and advice ?
thanks, robb
