I made this pattern myself when searching for a comfortable highly tailored glove for myself. It is made to fit me and does so well. Each time I make a pair of gloves from it I refine the pattern more.
It is made out of a blue thick almost cardboard like paper. (salvaged from work)
Fliped for other glove.
I found having a decent pattern helped but so much skill is required to make it work.
P.S. If you use this pattern please note me with a link so I can see how yours turned out
