I would love to be included in this either round robin or row by row. I have done a few round robins and you could also do a theme with them say someone wanted snowmen etc.
The row by row can get large so probably limiting the size of the height of the rows say having a minimum and maximum has been done with good success.
Another exchange idea might be a table runner exchange on a monthly basis just throwing ideas out there.
Please count me in on what is decided.
