Thank you ladies for the wonderful suggestions. The pieces were precut in the kit (thanks God) but i think i need to read the instructions again and see if it mentions the scant 1/4" because i was sewing very slowly to make sure my 1/4 seam was perfect. If you see in the pic how the points met at the end it would show how careful i was and when i was sewing the notches met with the melon and the arc so i feel that the melon is bit longer than it should. I am guessign when they where cut, they didn't follow the grain of the fabric.
So i will try the scant 1/4 and i will try to sew the melon starting from the middle and walk my way out and see how those work.
Thank you all again ;-)
