Interior Seat Covers

I got my seat covers for my 63 from Jake at Original Falcon, they look awesome. He bragged about how sturdy they are, and they are. However it seems they are so sturdy it is very hard to hide the big seem where the tuck and roll inserts, beading etc. come together. Wondering if anyone else installed their own and had similar problems? I tried building up the areas adjacent to the seam with foam with some success, however the slip over covers on the fronts will be next to impossible to do that with. They look very good, however I want them to look seamless and perfect. Am I being to picky? I looked back at some of the pics he sent me and notice wrinkling and seam marks in the some of the same areas that I am having problems with. Any advice?
