i don't think 90 x 90 is too big for a king at all. by the time two bodies get into it and the edges get pulled up, you'll be glad you have that size. as it is, it gives you only a 5"+ overhang. any smaller would give you none at all.
very nice and great work and can't get any more texas than that, can you? yeehaw :thumbup:
EDIT: a king top is 78 across and 80 down. so a 90 quilt across isn't that much.
can you make a new jersey quilt? same size, please.
