I fringed 2 shawls in 10 oz. worsted one inch deep for my 2 daughters, 54" on a side, and overcast the result. Did the same on a mini-plaid in 16 oz., 54x22. Took about 2.5 hours for each one, including the sewing. You get so you can pull out 3-5 threads at a time, especially before the fringe gets too long. If you're fringing for a kilt apron, it shouldn't take more than 10 minutes.
