Our Discord group (Stitching N Friends 22) is doing a band sampler in round robin style. A list is made of all participants and the round robin mailing route is established.
Each person (the owner) picks out a fabric and floss colorway to use for their sampler.
The owner then designs a band either 6 or 8 inches wide by .50 up to 1.00 inch tall (maximum) and stitch it at the top of the fabric.
(Note: Space for a header might have been left at the top above the owner's band if the material is long enough to fit all the bands. Headers/footers can be stitched after the sampler has made the whole circuit and is returned to the owner. This is optional.)
The owner stitches running sttitches at the beginning, center, and end of the band to the bottom of the fabric which delineates where the others should stitch their bands.
The owner stitches their initials in front of the band outside the starting running stitches and their state initials after the band outside the ending running stitches.
The owner then mails the fabric, floss, and any stitching instructions to the the next person on the list. (They always mail in the same order.)
The recipient stitches the band they have designed on the sender's fabric with the sender's floss starting 3 squares/t6 threads down from the owner's band.
The recipient then mails the band off to the next person on the list, continuing the sequence until a band has been stitched by every person on every band sampler and the sampler is returned to the owner by the last person on the list.
Here is a diagram of what the finished sampler will look like:
