I currently have 63 12 1/2" blocks done waiting to be put together. It will be a king size when its done. Will try and post pics later. I use all my odd pieces of batting.
We have had a one day quilt a thon doing these blocks. The local hotels donated sheets that they could not use anymore and we cut them up for foundations.
The second year everyone in the quilt group brought in all their scraps of batting.
The first year we did 550 and the second we did 330. From the first year we were able to make 22 quilts for the fire department to sell. They made over $5000 for their training fund for the volunteers. The second year we sold them and the proceeds were donated to a group that helps residents of the community in need.
Its a great way to get together and do something you don't have to think too much about.
