Thanks so much for the advice. I don't stretch the fabric at all when basting just smooth it over. There are no creases when it's done, it's definitely when I'm stitching. I think I will pin as well as spray basting and also look at how I support the quilt when I'm stitching, I like the idea of basting with water soluble thread, I'll have a look for some. I am wanting to have some form of suspension for the quilt. I don't think you can buy anything here in the UK and neither I nor my husband are particularly handy but I've bought some bungee ropes and clips and just need some hooks to go in the ceiling so I'll try that. Thanks for the links. I've unpicked the worst of the tucks and will stitch them tomorrow morning, I've been looking after my two young grandchildren today and then had to call on a friend this evening so don't want to attempt any sewing when I feel tired. Hopefully I will be more successful. Thanks again for the sharing of knowledge.
