I went through the cabinets and cupboards of my sewing room and found more things to pack into the stash box.
I found a couple of quilt patterns that I know I'll never make up, some zippers and buttons, an extra tape measure (I didn't realize I had a half dozen tape measures! And maybe more hiding around the house!), a book of patterns for quilt labels, a book of designs using charm squares, a magazine, and a bag pattern. These patterns are ones I bought several years ago on impulse and have never gotten around to making up, so they're like new in the packages.
I got a large postal box and have repacked everything and still have more space in there. I'll have to take another look around to see what I can add to fill it up.
