I never have. At the quilt guild I belong to, we used to have a block of the month. Everybody (well, those who chose to
participate, made the block and brought it to the next meeting.
Then there was a drawing for the winner. After the drawing,
a pattern for the next month would be given out and we did it
all again the next month. I think I have only seen two who
actually made a quilt out of their blocks. I won, one time, and I had to "frame" each one so I could cut them down then to all
be the same size. A quarter-inch doesn't seem to be the same
for everybody..right? I think most of them just get stuck back
somewhere. Incidentally, now a new block is made each month
but the person who made it takes it home with them..and the
same in the following months. They end up having enough of
their own blocks to make a sampler quilt. That seems to work
a whole lot better.
