Here’s a tutorial for a quick and easy quilt made from fat eighths. These are half the size of fat quarters, so what you could do is get fat quarters and cut them in half lengthwise, saving the other fat eighths for another project, or make two quilts at once.
Here is the bonus video that gives an idea for using up the leftover triangles. However, here’s a good tip to save time on this: When you make the diagonal line across the ends of the fat eighths for the “Fat Eighth Frenzy” quilt, draw a second line half an inch away on the small side where the triangles will be trimmed off. After you sew the line for the fat eight “diamond” piece, whip it around the sew on the second line. Now when you cut between these two lines you will have your unit for the “Fat Eighth Frenzy” AND a half-square triangle block all done both with a quarter inch seam allowance. You will still probably need to trim the triangle blocks to make sure they are all the same size. This will save time and save you the trouble of sewing on the bias of the triangles.
And remember – you can do all kinds of things with half-square triangles. Their idea is fine, but let your creativity flow. :-)
