I quilt in my lap and have sewn to my pants on many occasions. Not far - cause I can't turn the piece really quickly. I've cut wrong, sewed wrong, ran out of fabric - ok, well almost all of these things. The worst was when I cut ALL of the pieces I needed for a quilt and had reversed the lights and darks. Then I had to come up with an entirely new plan. Guess what ? It worked out great and stretched me to something new. Sometimes mistakes are the right thing to do. And - I feel your pain!
