An ambitious new embroidered "Burst"

I have been working on a series of embroidery pieces that I call "bursts" because they kind of look like an explosion (but burst sounds better - less violent). I finished this one today:

Now I'm starting this 50 x 50 inch burst. I am using a recycled fabric purchased at Arts and Scraps in Detroit during their recent fabric sale. My daughter and I spent almost two hours searching and filling our paper grocery bags for $8 each - an amazing deal! 

This might take me a while... :)
