A similar idea came to me when I purchased a small tea bag caddy at a craft show. There were a lot of tea drinkers in my series so the idea of using a tea caddy giveaway seemed a good promotion. The verse was perfect:
I cannot sit and chat with you the way I'd like to do, so brew yourself a cup of tea, You'll think of me, I'll think of you. I added
Tea goes best with PROMISE KEEPER.
I made templates of the verse and thumbnail image of the book cover, 10 to a sheet, and printed them. Preparation and materials included fabric, bows, using pinking shears and my sewing machine. I glued the verse on the front and the cover on the back. Everyone liked receiving this tiny memento.
Stretch your imagination or be a copy cat and I'm sure your readers will be impressed !
