The way I would do it is to sew solid squares on the rectangle
pieces and sew the three pieces together staggered then use a ruler cut the angle.

that does sound easier - for the next one. I went ahead and made all the pieces prior to testing it. What was I thinking!!!

Forgot to say stagger the rectangles before sewing.

Yes, whenever joining a straight edge with an angle, you always have a bit of hangover. The pieces should NOT be sewn together tip to tip...each side should have an equal amount. Actually, EXACTLY like it's shown in the picture in your book.

What would help you is this the corner/dog ears ruler.

I'm sure you can find a template...it makes sewing these types of shapes together really easy, until you get used to eyeing the distance.

How were the yellow triangles cut? HST or QST?

I am looking at your pieces, what they tell you to do, and the picture of the quilt.
If you look at the finished quilt. The middle pieces are put at the top of the left triangle causing the pieces to start angleing upwards, then do the same with the right. I wish I could draw a picture, but, look at the finished quilt closely and look how the center is placed on the top of the triangle, rather then where you have it

Be sure all seams are a accurate 1/4 inch, then be sure the "dog ears" stick out 1/4 inch each. I think that might help.

Stitch two together and right or wrong - take a picture and let us see what you have. (Before you rip anything back out)

looks to me like you are not allowing for the seam allowances. The pieces need to be moved 1/4" to the left so that a little triangle sticks out.

I will try to do that tonight, take a picture and post it tomorrow.

thanks.

Someone, I think did a tutorial on this recently.
