Impossible Geometry Socks

Job type Test knit

These socks were originally inspired by an Art Nouveau themed magazine call back in Summer 2021. After playing with various stitch swatches, what I got instead was a stitch pattern that reminded me more of the Impossible Geometry that is so prevalent in the works of M.C. Escher.

The Blocks Stitch Pattern is made with a combination of slipped stitches and one-over-four cables, this means that the leg and the top of the sock have far less stretch then the stocking stitch sole of the sock.

These socks are knit from the cuff down, with a heel flap and gusset style heel. The Blocks Stitch pattern is continued on the instep, while the sole  is knit in stocking stitch, and the toe is decreased and then seamed with grafting (Kitchener Stitch).

Requirements from the maker
  • Left and Right socks are identical so only one sock is required for the test
  • You will use your own yarn, but get to keep the finished object. As well, you will get a final copy of the finished pattern for your own use.
  • You will not share or distribute the pattern PDF.
  • You will be able to complete the test by the deadline posted.
  • If circumstances come up and you cannot complete the test by the deadline posted, you will notify me as soon as possible.
  • You will post any errors or other issues you encounter with the pattern to the testing chat
  • If you are altering the pattern to your own preferences, please post to the chat thread, or message me here on YarnPond to confirm. I don’t usually mind alterations, but I do have to make sure that the elements of the pattern I need tested are being tested.
  • I would like to have feedback posted the chat once every two weeks, minimum, please. That feedback does not have to be elaborate, it can even be ‘I haven’t touched this since last time’.
  • Finished Projects should include a photograph. While I would prefer modeled photos (if applicable), this is not an absolute requirement. I may ask for your project photograph to be featured on social media, if I like it, but that is not a requirement of my testers.
  • Testers should fill out the feedback questions when they have completed their project.
  • You may create a project page on Ravelry at any time you wish (also not a requirement).
