I'm not sure of the time exactly. It was 3 weekend days to piece the dahlia. I sewed 1/4 of it on each of two evenings onto the background then did the other half on Saturday. On Sunday I cut out the applique and layed it out. Oh, plus the time of laying out the background on the floor and getting it cut and pieced then laying out the dahlia and starching and pinning it. I'd have to look back at posts to see when I started it... a few weeks ago. I procrastinate about the background for a week or more though.
The background is Hoffman, Love Is In The Air. It's a white-on-white with a silver (Pearl) sparkle. The dahlia fabric also has silver accents.
