Arianaquilts, the pattern on the last one is Anita's Arrowhead. It is a really cool block; there are free directions if you do a web search. Also if you do a Pinterest search you will see a myriad of options for it. Using black as the consistent color gives it a certain look. My DD and DDIL both have told me they love that quilt better than any I have made ever (so I probably need to make another in a different color range before Christmas!).
Thanks so much for all the good feedback on these...my husband rarely shows any interest in my projects but he is happy with the quilt for our bed. And all three make me happy!
