Felted mittens

I am new to this forum, but have used the web-site for help with knitting teqniques a couple of times.
Now I really want to make some felted mittens for my dads birthday, (he is a sailor, and have told me how good they are for keeping you warm even when soaked in cold sea-water :smiley: ). I haven’t got a pattern, but i know how to make mittens in general, and i just love the knitted sailboat cloth pattern. http://www.knittingknonsense.com/sailboatcloth.html
Does anybody have an idea as to how that might work and how much (approximatly) a mitten shrinks when felted?
(I was thinking of knitting the pattern with a double thread, possibly in two colours to make it show after felted, but have no idea if it will work…)


Here are some patterns for felted mittens. Maybe you can use them as a guideline?
