Thank you to Margaret, Adds and Anita for helping me ot find the fabric! Margaret and Adds both pointed me to the very site I'd linked to - and they were right! I'd assumed that N/A in the information meant the fabric wasn't available, but it seems that it meant that some of the information about the fabric (the designer) wasn't available. I now have lot of lilac and some pink, green and aqua on the way, and, with many thanks to Anita, a link for the navy as well. Anita even managed to pick up some lilac in her searches for me!
Thank you my blogging friends!
