It's easy to add an inseam pocket to a garment. The pocket is shaped like a teardrop with one straight side about 8" long. The pocket drops below the end of the straight edge. Sew one to each side of a seam (the same distance from the top (or hem) using a 1/4" - 3/8" seam allowance (press seam toward pocket). Then sew the seam, pivoting at the top and bottom of the pocket to include it in the seam. Press the pocket toward the front.
There are ways to work with damaged ties. A small hole can be patched with a piece cut from elsewhere in the tie and fused over the hole using fusible web, stitched in place with matching thread. You can also patch with a tie label, stitched over the damaged area. Ties weakened by wear can be reinforced with a light-weight fusible interfacing on the wrong side. Many faded ties can be used by turning inside out and using the wrong side.
