I decided I was determined to get those pieces to meet up. I took out two pieces of the center so I had 8 pieces on each side. I aligned up the center in a swirl, pinned the two halves together and started sewing down the middle. When I got the center, I carefully went through the middle of each section and then came out the other side and finished the seam. It's not perfect, but I figure if it doesn't look great, I can sew in a beautiful pink or blue button that would set off the center.
I still need to sew the other half of the center to the dahlia petals, but the center is pieced. I have the outside to work on and then figure out the background.
I'm crawling back into bed now. This has wiped me out and it took me about 20-30 minutes to do this. I may see a doc tomorrow about being sick. Thankfully; I don't have a sinus infection but this isn't getting any better.
