not sure of the name either, I just use a whip stitch on mine
Luckily Queenie told me the name of the stitch, it's glove stitch.
Could this be the Glove Stitch? Whatever its name, it's neat!
Thank you Queenie, you're right. In English it's called glove stitch.
Funny it is not a TAST stitch, but I seem to know it!!!
