many of the "designers" featured in the magazines use collections fron a single manufacturer and usually their latest designs. I have in the past done this and was encouraged to use as many of the patterns as possible.
The churn dash I made (mentioned in another post) contained every print in one line. The instructions were difficult to translate as I didn't have access to so many prints and it took awhile to assemble enough to make the quilt even similar to the one in the magazine. The pattern was used at a retreat and the attendees wanted to know how much fabric they needed from their stash. My My what a job to calculate amounts when I didn't have 1/2 yd cuts of all the prints.
