Something we tried this year was a Retreat Challenge Round Robin with the finished blocks being revealed at the retreat. There were two challenge fabrics available but when we chose which one we only knew the colourway and not the actual fabric. Here are the two fabrics that had to be incorporated into the blocks:
I'll share what I did on the blocks I worked on later but in the meantime here are some of the finished blocks as we saw them at retreat. A few were not completed in time and are going back for more stitching but it is interesting to see what everyone did with these fabrics.
