Pick-up sticks, or pattern sticks, are a neat way to do patterns using floats or supplementary weft. On rigid heddle looms they’re a way to introduce a whole range of different patterns and textures, including making “lace” and things like waffle weave.
So, what are pick-up sticks in weaving? A flat stick that is wide enough to give you a useable shed, when inserted between warp threads and turned on its edge. Though my first pick-up stick was a spatula! (I was impatient to try the technique.) And many weavers repurpose stick shuttles for this.
Generally you put your reed/heddle into a down-shed and then slip the stick under the desired slot threads behind the reed/heddle (e.g. under every third thread). You then alternate weaving normal tabby picks and pattern picks where you put the pick-up stick on its edge to create a shed. There are plenty of videos online showing how to do this, so I won’t go into it too much, but here are a few pics to give you an idea:
It is very easy to miss a thread when using pick-up sticks and I found it helped to put a piece of stiff paper – in a contrasting colour – under my slot threads, so I could see them clearly.
Some people actually pick up in front of the reed/heddle (easier to reach), turn the pick-up stick on edge to create a shed and then insert a second pick-up stick into the shed behind the reed/heddle, finally removing the first pick-up stick.
I must say it makes me nostalgic for the more commonly known kind of pick-up stick!
