My photo inspiration appeared to be a little more graceful than a 60 degree triangle and sure enough, it was NOT 60 degree! Thank goodness I checked before cutting - it turned out to be the size of our Tri Recs ruler. (The 60 degree triangle would also work - just a little chunkier. ) The Tri Recs has two sides that are longer than the base. This is coming along very quickly and easily. The large triangles are cut from a strip at 4 7/8 in. The little ones are 2 7/8 in. strip. One must be careful to keep the base along the straight of grain - won't work otherwise. The 2 straight of grains are sewn together first. Also, pressing the seams open works best on this design, and must be done gently.
I used stash, and decided to keep 4 of the same combos together. Also note that all the darks are on top while the lights are on bottom. Mixing them up? - I didn't try. For fun, I included a few little ones, half size - they also went together very well and might be good in a border.
Such a simple design, yet like all blocks, there are a myriad of combinations. These colors are subdued. I had hoped to have less contrast but this is what I had. It'll do!
