All good suggestions so far. I will add a couple more: I staple the ends first making sure it is pulled fairly tight and centered. Most seats have a dip from front to back so when you pull the cover tight it will raise the middle of the seat cover off the foam but that's ok. I then do about three staples in the middle of each side pulling it tight. I then go back to the ends putting 2-3 staples at a time in an alternating pattern : left front, right front, left rear, right rear. If wrinkles develope as you work back to the center just remove the center staples and pull it tighter and staple again. I used 3/8" (10mm) staples the last time (because they were all I had on hand) but had to carefully angle them when stapling the ends so they wouldn't stick through. A regular stapler will leave some staples not seated firmly but that's ok just tap them on in with a hammer (do not wait till the end of the job to use the hammer - seat each staple before going on). Hope this helps. - Ken
