Here's where we do the Happy Dance!!
Ariane has done a tutorial on a Triangle in a Square! Check out her tutorial - she has done a great job of explaining how to make these and even gives several sizes.
How cool is that?
Ariane's Triangle in a Square blocks - Look! She made different sizes!
With a little tree trunk this could work . I'm not sure if the size would be exactly the same as the one in the Little Forest pattern. I've been thinking of making the quilt a lap size, so for me this would be a good method.
I just thought you might like to know.
