The method using the rulers is a little confusing. For me I had to learn not to go by the shape of the ruler but by the name of it. Also she does have a lot of ruler sizes so it can appear overwhelming. The first thing I did of her was the project that came in the little floral suitcase. I had to go back an get extra fabric several times because I cut something wrong. But I am glad now I persevered. I use the half square and quarter square triangle method on almost all blocks like that. I have determined though I do like cutting blocks just a little larger then squaring them up.
