I have two pin size holes in a pair of suit pants. The holes are probably 1 millimeter each. They are nonobvious, but I'm concerned that the holes could get bigger, which is why I'm thinking about repairing them. The first hole is right above the cuff on the leg. Because there is no lining, I'm wondering whether an iron in patch would work. Because the hole is so small, the patch won't cause any cosmetic difficulties. But is a patch the right/cost effective way to go? The second one is on the back side of the pants just below the belt line. The problem here is that to repair the thing from the inside, you'd have to unstitch the back pocket and then sew it back on. Could a tailor just put a small stitch in the hole from the outside? Also, do you find that repairing 1 mm holes right away is the thing to do to prevent future problems (because these holes are not cosmetic blemishes in any way). Thanks.
