Feeling a strong desire to get the edging started on the hanky Diane gave me, I opted to begin with someone else's design rather than create one of my own. (I think I have enough design projects underway already.) I chose Mary Konior's Beaded Braid (page 9 of Tatting with Visual Patterns). Ignore the single ring. Mary's pattern has the clover with the bead at its base repeating over and over again with a final round of chain to finish it off. With my little practice piece of edging, I can already see a need to lengthen the chains between the clovers. I have some ideas for the corners and rounding the largest part of the scalloped corner.
After adding the round of chain scallops on the outside, I think the tatting will be the same width, or slightly larger, than the "ribbon" of the corner. And even though they don't look it in this picture, the beads are white. What do you think?
