I like to sew my strings onto a 8 to 10 in base block. Then you simply use your scraps and pin first strip in the middle of your base block. It will be face up. Then grab another strip and lay it face down. Sew the second piece over the first. The one side only. Flip it open and get another strip, lay it over the edge of the second piece. It starts out face down, you sew that one side. Then open it up. You will have the beginning of your scrap quilt block. Just keep doing this untill it covers the corner. Pin. Turn the block around and do the same. Now let me tell you some of the prettiest blocks use all sizes of strips, and any color or print. When you get the first block covered you should be able to handle it from there. Its fun and besides you will have space for more fabric when the strings are all sewed up. Our mothers probably did this during the depression because they had to. Now we simply enjoy doing it.
