Thank you all for the suggestions
I ran to JoAnns and got some variegated red/white/blue Coats and Clark quilting thread. I know it's not premium thread, but I hope it'll work ok. Even was able to use a coupon on it!
While I was there, I grabbed some batting for the Craftsy Mystery Quilt I'm doing (50% off) and a can of June Taylor basting spray (used a coupon). All-In-all, not a bad shopping trip
