I finished a whole cloth quilt several months back. It was a full sized quilt and the hardest part was picking and marking the design. I used freezer paper and butcher paper, marked 1/4 of the quilt at a time working from the paper that I taped to my husbands pool table, laying the quilt top over it, and tracing. After that it was quite easy.
There are lots of books and patterns out there. I used a book from Fons and Porter and they made it a lot easier. It was lots of feathrs and the methods to make your own patterns was easy to follow. If I can dig it out I will send you the name.
You will enjoy the process and the result I feel sure.
Good luck, Pam
