Use a smaller than usual stitch length when piecing. I remove paper as soon as possible because I feel the sections don't piece together as accurately with it remaining. Crease the stitching line before trying to remove paper. I run my fingernails over the crease and also make good use of sharp tweezers in getting the little bits out. (I actually hate the tedium of removing the paper but realize that paper piecing is the best way to make certain things like pineapple blocks)
