I made satin pillowcases for my dog's beds and pads (about 7 cases in all). He is a Maltese and his hair can get to be a tangled mess. As Tartan suggested, I did use Elmer's school glue in the seam allowances instead of pins (the pins just slipped out and were pretty useless). The glue worked great! I did French seams also to tame those raveling edges but I haven't washed and pulled them on and off of the beds much so I don't know if I used too large of a stitch and if the seams will start coming apart or not as mentioned by dd.
