@Iminei Each participant gets a piece of fabric from each of the other participants.
They then make up a 12.5” block for each of these fabrics, using own fabrics in addition to the gifted fabric.
These blocks are then returned to
@RJR_38 who collates all the blocks and forwards the participants all the blocks made with their own fabric.
The participants can then make up a quilt using all the blocks returned to them.
