A WALKING FOOT! That is my only tip. It stretches a BUNCH.
So I would say once you lay the right sides together pin pin pin and then add a few more pins, then use the walking foot to sew it around the edges.
Yes it causes a bunch of lint but I wouldn't worry about it until you are all the way done, then just drag the vacuum out to clean up, don't try do sweep it cause it just flies every where!
Good luck.
