Well, that is really questionable in my opinion. I have never enjoyed hemstitching. However, I have 2 really good tips to make it a little easier.
The second tip improves your visibility for hemstitching. Depending on the color of my warp, I find that seeing the warp ends and counting them correctly can be challenging. I place a contrasting sheet of paper UNDER the warp, and voila: visibility improves dramatically.
I have been happily weaving since my son was born in 1988.
