It's the triangles that I couldn't get the right size. I used scrap fabric and finally figured out they didn't include the cutting instructions for the humps and the background. I needed to cut 3.75" squares, halve them for the humps, another one of another fabric for the background between the two humps and I used scraps to make the side pieces. I understood that you needed two colors of fabric, the picture shows that.
I agree about not cutting to 7/8".....I rounded up to an inch each time and ironically, it worked better than the 7/8" cutting!
I did go into "contact" and tried to ask...didn't see the e-mail address. I don't think I'll make another one!!!!!!!
