An expensive hole maker (in your clothing)

BH...nice kit.

You could mark a scale on the box to reduce bulk and free up some space inside for her. Once you do that, make a small roll of unmarked paper tape about 2 yards long and anywhere between 1/2 - 1" wide or so. That extra space...there's another use for it.

During the 18th century, tailors didn't rely on marked rules for taking measurements. They used the roll of blank paper stripping as a "memory stick" by placing an end, or marked spot on the tape and stretched it around chests, waists, along arms, etc, and made notations of what marks were related, and how. The tape measure is a 19th century device, however you can see where the idea came from. The "memory stick" method was used in woodworking and similar trades during the era, and gets around the use of a ruler. String or thread can also be used for the same purpose, however, the rolled/coiled paper strip can be kept for re-use (on the other-side) or to make additional items to fit the same measurements.

Harbor Freight sells 6" scissors of the same type you show in the photo. They run about $5 without a 20% off coupon, and are cheaper there than some of the vendors sell them for. You can get her a spare pair if those dull out. A small leather sheath for the two forks of the scissors are good to make next time you get bored, because they prevent getting stabbed if you forget where they are and get the wrong end by accident.
