Thumb on a mitten after I shapped the gusset
(Fremont California )
All sizes: Next row: (RS) k 21. Turn. Cast on 2 sts. Slip remaining sts st holder.
***Thumb:Next row:P10. Turn. Leave rem sts on st holder. Continue in stocking st on these 10 sts until thumb from cast on row measures 1 “ ending on a purl row.
My question, what needle do I put the 2 cast on sts on? And do I put them on a st holder with the rest? I’ve torn out my work multiple times cause it doesn’t look right. Please help.
