I’ve been sewing for about 14 years now, so I have a pretty good pattern stash. I don’t know of a free pants pattern, but I bet if you google it you could find one. There are som GREAT patterns for sale and download (you print them yourself) at etsy. I’ve been using them a lot lately and have been very pleased.
And happy winter to you, although it is 80 degrees here today. Stupid weather!
