Ok KP friends. Plz help thaw the brain freeze I'm having. I knitting a pair of handwarmers and I want to add the flap that you can stick your fingers into and convet them to mittens and I can't remember if I do decreases to get rounded top or just knit a rectangle and when I turn it right side out will get rounded top that way. Any pattern suggestions would b greatly appreciated. Using a basic St st for glove. Thanx in advance.
