The pattern is written for an 8" palm, but there are notes on resizing for a smaller or larger hand.
My calculations show these take approximately 140 yd of main color and 63 of contrast color. Two balls of Palette will be ample to make two pairs if you reverse the colors for the second pair.
The blue/grey pair shown are in Palette, but any fingering can be used, of course. The olive/gold pair were done with leftovers of Scheepjes sock yarn and an unknown.
