Summary:

The feedback is strongly positive overall, with customers saying the papers make half-square triangle blocks easy, accurate, and precise, and that projects like pinwheels and HSTs turned out really well. A few noted useful details such as clearly marked lines, included instructions, and the availability of different sizes, and one customer said they would use them again in other sizes. The main criticism was that the paper could be thinner, and another customer wished the outside of the package showed the fabric square size needed for the pattern.
