Nancy,
thanks for the reply--I did not want to move forward on stitching the star to the circle until I received some advice. I did follow instructions and put the two outer borders together with a loose machine basting first but I did put the border on the bottom and it did not turn out as perfectly as I would have liked; ergo the email out for help.
This time, I went back to something I remember from childhood in Italy... in my mother's atelier, seamstresses would hand-baste with basting thread the pieces of a garment before the first fitting... so, I pulled out some basting thread and because I did not like the way machine-basting did the circle, I meticulously basted the star circle to the second circle by hand. This time, everything was perfect, no need for easing anywhere because I was able to pull the thread through from front to back and vice versa on the marked lines on both sides. But, with your posting in hand, now I can sew the seam with the circle on top. Makes sense, won't chop off the points.
On an aside, I actually used Carol Doak's foundation paper. I was a little worried that it would tear and not hold up to the end. I was wrong! At the end of month one, it is still standing and I know it will tear off easily when the time comes. For those who had difficulty with the thickness of the paper when assembling the circles because of paper in the seams, I would say, do a hand-basting first--everything else will fall into place.
Thanks for your help. I'm ready to go. In the meantime, I've picked out the gradations of grey and beige for my triangles, printed out the triangle papers and am ready to go.
Cheers,
Renata
