Each of the 37 blocks in this book has a double, albeit with different fabric placement. Design your own quilt/table runner/wall hanging or quilt with the blocks of your choice for a totally unique project. You will not be making all of the blocks shown in the book (unless you always like to make king size quilts and feel cheated if you don't take advantage of everything in the book!) In other words, don't feel obligated to make a quilt the size of the classroom sample. Blocks are make by straight piecing and paper piecing and finish at 12". Come to class for color ideas, tips on piecing, to socialize or just to have a boost to complete the quilt. You will not regret owning this book as it is full of fabulous ideas.
