I now carry "Thangles" in all 15 sizes. A few of the new patterns I was working on called for them in the instructions so I thought I give them a try. In case you are wondering what they are they are strips of paper that you lay on top of your fabric and sew and then cut apart to make accurate half square triangles. They are really easy to use! They come as small as 1/2" to as large as a 6" square. Price: $6.00 a pkg. (a pkg of 2.5" finished has enough paper strips to make 300 half square triangles).
