It had to be done! I have very limited quantities of the minisock rulers avaliable in some of the halloween acrylics; holo bats, orange hex, neon black stars, and pink moons (from second left to right in the jumper stitch marker image)
They measure 22cm long, and only 6.5cm wide (standard sock rulers are 30cm x 9cm). They also feature UK, EU, US men's and women's size information.
