Just like I said yesterday, before you start sewing, really pre-quilting step one, is to organize your scraps. Having your scraps organized makes them sooo much easier to use and be inspired by. So, scraps organized? Good! On to the sewing!
Step 1 is to pick two contrasting colors (or color groups) for your quilt. I chose muslin and blue with a bit of green. Pick a size of square to start with. A 5" square will yield finished half square triangles of about 4" square. It doesn't really matter what size you choose to start, as long as they are all the same. You will need half as many squares of each color as the total number of HST blocks the finished quilt will have. (So for an 8x8 layout, that's 64 blocks, meaning I need to cut 32 squares from each of my colors.)
Step 2 is to go through your scraps cutting squares of your chosen size until you have enough. If you start running out of scraps large enough to get a square from, you can also cut triangles half the size of your chosen square. 2 triangles = 1 square.
(Method #2 here details the technique we are using to make our HSTs)
Step 3 is to begin sewing your HSTs. Use a pencil and your ruler to mark a line from corner to corner on the back side of all the squares of one color. Then pair up the fabrics with the opposite color, right sides together, and sew 1/4" to either side of the line. Cut the blocks in half along the marked line to yield 2 HSTs per pair. Press and trim if desired (I hate trimming, and since this is a scrap quilt anyway, I just let it go.)
Step 4 is to arrange your blocks on the design wall. In retrospect, I wish I had tried more to keep the blues similar where they touch. Oh well, just an excuse to make this design again! When you are happy with your arrangement begin sewing the top together. I prefer to sew this type of quilt together but grouping the small blocks into larger and larger blocks, rather than rows. It makes it so much easier to make those points match!
That's it! There are plenty of potential variations to this design. Try going for rainbow colors, or creating a gradation across the quilt.
