I am getting into lace borders and edging now.
This particular design is easy to memorize but not boring.
You decide how long you want the lace pattern to be by repeating rows 1 and 2.
Then you finish off with rows 1A - 6A.
The pattern begins at the bottom so if you are knitting a top from the bottom up,
you would knit the lace edging first.
You also could knit this edging and sew it on a completed garment.
I think it would make a nice edging for towel. 
The pattern and chart are for flat knitting. If you knit this in the round,
you will have to make adjustments. 
The pattern can be found on my website.
