Here is another option for making a jelly roll race quilt, as they are sometimes called. This lady did hers using up scraps from her own stash. It gives it a much more scrappy look but, as with this one, it also allows for using a group of fabrics in many shades of the same color. This gives it a more unified look overall, I think.
As was mentioned on a previous post here, some people recommend cutting your extra fabric scraps into uniform sizes that are commonly used in quilt project these days – 5” charms, 10” squares, 2 1/2” strips. This makes it easier for you later. Whether you get out your scraps and have a cutting session, or if you cut the scraps into these sizes at the time you make your original cuts (for a quilt or clothing project), it will save you time later and make projects like this much quicker. [Note: I recommend only cutting scraps from clothing projects made from quilt appropriate cottons.]
The music is kind of neurotic. I like the William Tell Overture for this better. :-)
