I usually make up my own combination of blocks and fabrics.
I did order a few kits when I first began quilting and was disappointed in the quality of the fabric so I was turned off on them. They weren't from known quilt shops.
Was completely happy with the kit I ordered from Keepsake Quilting about 2 years ago. It was a off centered log cabin quilt, just one huge block that I wanted the pattern of, and it was in just the right colors for a friend of ours.
Haven't ordered but I do like many of the Connecting Threads kits, they seem to have plenty of fabric for the price and many quilters give them good reviews. May in Jersey
