"45 Degrees" by Cathy Perlmutter features a design comprised of 45 degree triangles.
Cathy's 45 Degrees quilt is the type of work that she is doing now that features, as the title would suggest, 45 degree triangles. These triangles can be played with in a similar improv way to 60 degree triangles, with Cathy finding the 60 degree ones to be more liberating in terms of design while the 45 degree ones can be a little bit more complicated.
