I am fairly new to sewing, but I do want to make my own yoga/gaucho pants for the dance classes that I take. I saw a tutorial on threadbangers that I thought was decent/doable. I just don't know where I can get tracing paper. I looked at Joann's last week, but all they had was small stuff - nothing big enough for a pair of pants. Do you buy yours at a brick and mortar store or online?
