It's my first Project Linus quilt and uber cute! I have a Sulky rayon thread (100% viscose) that would work well in terms of color, but I've read that rayon is not as strong as cotton or polyester and I've never quilted with rayon before. Will it be strong enough to stand up to the multiple washings for a Project Linus quilt? I don't have other colors on hand that would work, so it means a trip to the store if this isn't suitable.
Edit: Oh, and the pattern calls for straight-line quilting. Would a serpentine stitch be okay?
