Hi Anita,
I just finished quilting my King Sized Hour Glass quilt using size 10 Crochet Thread, size 22 Sharp Chenille/large eye needles and "Big Stitch" quilting. I LOVE IT!!!!! I just finished the matching pillow shams and am figuring out a bed runner, then I will post All, together as a matched set. But, check out "Big Stitch quilting on Pinterest and see what you think. Most that I saw were using size 8 Pearl crochet thread, I tried some and it was just that little bit too big, you had to use a larger needle, like a size 20 or 18 and it was too much work to pull through the fabric sandwich. The size 10 with a size 22 sharp was perfect, (and cheaper, and way easier to find!) Good Luck.
