Fabric and books are items I definitely buy from USA . Nancy notions may give you a few ideas as she does have new tools . Also try quilt in a day. I find here in UK not much choice in fabric which has square with a theme ie, ladies sewing etc.
I would also look at rulers twister square a big one which has slits too cut out shapes.
Cheaper item over pond definitely quilt cal. Also 505 cheaper.
They may have patterns which are new ideas.
