Now here are a couple of other ways to make the Bostons
You can use strips to join the top two fabrics. Cut them at least a bit more than half the width of the template on point.
You can cut the joined strips the size you need. For the 1 1/2" Bostons the strips need to be cut at least 1 3/4" sections. Then use the sections and sew on the third fabric to the edge. Make sure you place the medium on the side it needs to be for the color placement you need. As in the mirror image blocks.

Another alternative for those who want to take the time to save a bit of fabric you can cut squares and then cut them into triangles. For the 1 1/2" size you need to cut at least 2 1/4" squares. For the third or bottom fabric cut the squares from corner to corner for two triangles. And for the quarter triangles cut the same size square but cut them into 4 triangles from corner to corner.

This will allow you to have less leftovers.
Speaking of leftovers. - I never worry about leftovers. I reuse the scraps into other "Blocks" or make more Boston Blocks. You can also use them to make crumb blocks or crazy quilt blocks.
One thing I hear alot is what about Bias. I don't pay any attention to the Bias edge. Yes you will have sides that are cut on the bias. But if you tack then you dont' have to worry about Bias edges.
I tack where seams meet and I tack on the edge of joining two blocks. This keeps the fabric from moving so no stretching. I think tacks work better than pins. Pins can still move but tacks stay put.
A tack is a stitch or two in place. Put the tack where the seam is going to go through. then you don't have to take it back out.
