they are very easy to make. I went to a thrift store and searched through the sweaters to find some wool ones that i liked. These two pants were both made from Lg sweaters. I cut the arms off at the seam. Then I looked at a couple of pants my ds wears. I measured them from the crotch to the bottom of the leg. Which was about 9 inches. Then i measured from the crotch to the waist. That was about 9 or 10 inches too. So i took the arm i cut out and starting from the top, I cut the inner seam until it was about 10 inches from the end of the cuff. I did that on the other arm too. Then I serged the two pieces together. It looks like little pants at this point, but the waist isn't even. The outer edges are higher and pointed. At this point I measured from the crotch up about 11 inches. And then I serged all around the crotch so that the top of the pants are now all even. Then I folded and sewed it down, and put in the elastic. I think elastic is quicker to put on ds. And then that is it, all done!
I haven't lanolized them yet. But he has been wearing them the last couple of days and they haven't even gotten damp! I love wool!
Give it a try...it doesn't take very long, less than 45 minutes. Let us see your pants when you do!
(sorry if my description doesn't make sense....I have never been very good at giving instructions, or listening to them for that fact! :LOL )
