It'll probably be a few months, but thank you! I am honestly a bit bewildered as to why so many people are telling me sternly that I mustn't quilt it, as I've said repeatedly that I'm looking at this afresh rather than taking the traditional approach. The piecing is no more complex than any other quilt that I've made, and apart from a few bits of foundation here and there which I can easily work round, the top is no heavier than any other standard quilting top. My seashell quilt top is the one that'll be really hard to quilt through, as the pieces are all tiny and there are seam allowances everywhere. But anyway, everyone's being very helpful and it's nice to get so much input.
