Update and question. I think I've de died what I'm going to do and now I have another question. I remeasured the top and it is actually 100X100 so King size. I'm going to sew the bottom edge RST with the sheet and then flip so the bottom is finished. Then I'll stitch the top down to the sheet. I can't find a fleece blanket big enough (King are mostly 108 X 90) so I'm going to buy fleece and have a seam. Does anyone have experience with any online sites for buying anti-pill fleece at a decent price. I'm tempted by Wal Mart online for $4.97 per yard but will have to stop in the store to see how it feels. I'd hate to order 6 yards and not be happy with the quality. Thanks for all the suggestions.
