Pat, you will be sending your row to TheMamaHauser first. If you are ready to send, I think you could PM her and ask if she is ready for it. Or just hope she sees your question on this thread. Either is fine.
Judy, I am enclosing sashing strips with my row, too. I'm hoping it's OK with everyone. No one seemed to object. I'm also sending along fabric scraps in case someone needs them.
To all -- as for gifts to be sent along, I think it is entirely up to you. You will send to the same person each time so I would think you would not need to enclose a gift every time if you decide to send a gift at all. I think you should do exactly what makes you happy.
