My daughter is 5' 10" and suffers from having a mother that taught her to value modesty. While most moms, and certainly most teens, would not care that a skirt hits the leg 3/4 the way down her thigh, we do. When the leg is long that is still a lot leg.
Since almost everything is covered in lace these days and I make lace, I decided to make an edging to go around the hem of the full skirt. She picked out Ann Orr's Wide Pointed Edging from her book Classic Tatting Patterns page 24 which when tatted in size 20 is 1 3/4 inches wide. Her skirt needs to look 3 inches longer. So I had to modify the pattern. I added a 6 double stitch "bridge" so I could add a repeat of the square motif or two or more. (I practiced by making a bookmark.) One side of the square motif is made followed by the bridge, then start the next motif. When the desired number of motifs have been started, complete the last motif. The last chain will lock join to the base of the first ring. Then bridge back to the previous motif, lock join to the base of the last ring of the motif and finish the motif.
I have to say this is probably one of the trickiest designs I have tried. The transition from the point to the second row of square motifs has tripped me up several times. I have reached the end of the repetition only to find that I do not have a place to join to because I messed the transition up. I have had to pick out the entire second half at least twice. That is really not fun. It takes about 15 minutes to tat, but 5 hours to pick out.
I need to sew the ends of the bookmark in still, but you get the idea.
