Wear them inside-out. Take a crayon or marker, and draw a line on both legs to show how tight you want them to be. Remember to make the line on the inside so when you wear them you can’t see the seams on the outside of the leg. Make sure you draw the line on the opposite side of the manufacturer’s original seam. You can use pins to tack, but you might end up poking yourself or the pins might end up coming out when you take the jeans off. As an alternative, take a pair of skinny jeans you already own as a guide. Spread out the pair you want to reconstruct inside-out and lay the skinny jeans on top (lining up the crotch). Make sure the seam is evenly on the edge (of both pairs) and take your chalk down the side of your pants, starting about mid-thigh, mirroring the line of the skinnies. Iron your jeans first to make everything easier. Flat, unwrinkled jeans are easier to work with.
Start on the seam that is already there, backstitch a few times, and carefully follow your line all the way down making sure the edge of the denim remains flat. (Pins work for that. )[1] X Research source www. lovecharlesvintage. blogspot. com/2012/01/diy-tutorial-how-to-make-skinny-jeans. html If you’re using a sewing machine and concerned the first go-round may not be ideal, set your machine to the loosest stitch in case you have to take it out.
If you’re unhappy, remove the stitches. But if they’re tight, short, and spaced closely so that there are no bumps in your jeans and the stitches won’t be pulled out in the wash, you’re good to go. Work over each stitch as perfectly and as carefully as you can – there’s nothing worse than having a brand new pair of skinny jeans for one day and then having the stitches all pulled out the next. This will be hard work, but it is essential.
However, you might want to wear and wash your jeans at least once before you start cutting them up, in case you want to go back and fix something later on.
While you have your seam ripper handy, rip apart the jean thread that’s about one inch on the outside of the seam markings and everything in between those two. This will take a minute to do well.
Then put pins going up the seam and remove the bottom pin. Unfold the entire cuff so you’re able to pin it together, top to bottom.
Cut off the excess fabric and fold the cuff back up. As you fold it back up, make sure the raw edges of the seam are opened–if they’re closed, they’ll get bulky and bumpy. Pin the cuff to the pant leg. Adjust your sewing machine so the needle leans to the left and use the zipper foot instead. You want to get as close as possible to the seam. Hold open the inner seam and sew all the way around the pant leg as close as possible to the original seam. Try them on after this step – you may find that they’re too long or too short and you can go back to adjust. If there’s too much fabric on the end, zigzag stitch and cut off the excess or use a serger. Iron the leg of your jeans. Use a high heat setting and flip the pants so that the inside excess fabric is pointing upwards (toward the crotch). Go over this area several times.
