HI!!!
I just made skinny jeans (took old-fashioned regular jeans and made it into skinnies) but I am having a bit of problem next to the crotch area. Like I save getting holes there because when i sew and cut the excess material I don't know how to cut at the top and end up making a hole!
Please don't be embryonic about it!
How do I put sealant around the hip...
Answers:    I'm somewhat confused with the "cut at the top" division, but if you notice surrounded by your jeans that aren't altered, there is a "cross" contained by the crotch. A lot of people freshly sew one seam across this area when tailoring and finishing up with a hole because it have to cross in proclaim to keep the four separate pieces from pulling away from eachother....
