Nice to know there are some 7"ers forging ahead and I can be guided by your experience.
I love the look of the Razzle Dazzle in the pics but have yet to see it in the flesh. All the blocks posted have beautiful fabrics and work in them. I don't think I am up to bobbin work though.
Having done cross-stitch and embroidery I have lots of DMC and decorative threads but nothing for applique (apart from the 3 colours I am using for the Penny Haren BOM). We have the Australasian Quilt Convention coming up soon and I am hoping to get some threads there.
I have also used Norwegian Formula. Great stuff!
