Hello, all sewers out there. I have a problem with the length of the pants. Everything on the top (hips and waist) is fine but they are too long. I have already done the sewing (i.e the sides etc, but they are not finished at the bottom or the top where I put the elastic). So all the pjs have now is the pant shape with too long legs. Is there anyway to shorten them now? can I cut off the bottom fabric in a straight line? do I measure this from the crotch. I know this is a bit of a disaster; I should have been more careful with the paper pattern. But alas. I'll do that next time. What should I do now??? please help. It looks like I need to reduce by about 1.5"
