I do this methodfor my toe up socks.
That site explains the Japanese short row without pins method.
the site explains the heel and i have made it into my toe as well....(like my toes and heels to match.)
I still do cuff down with gusset...but only for my MIL and husband because they need the support.
I like toe up cuz....
you can split the yarn you have to use into 2 balls and just knit till there aint no more in one ball....
and you can try them on as you go...less chance for sizing errors.
I like the sturdyness of my toes and heels with that method
and they look good.
Good luck with the toe up!!!
