The basic pattern for two contrasting colors A and B is

meaning one loop (two threads) of A, one loop of B, and so forth.

​Repeating this pattern three times gives a warp of 21 loops with the sequence:

The key to this pattern is the repeat of two loops of A that break up the straight alternating ABAB sequence.
Once the frame is set up, the next step is to work consistent 1-1 interlacing. I started with treating the first row as a normal plait row but found that I exchanged the two edge threads, messed up the careful arrangement, and didn’t get the desired pattern. In order to keep the threads in order I came up with the following sequence:

Instead of picking up both threads at the beginning of the first Z row I place the first thread as a back thread and pick up the second. Carol James calls this first thread a bachelor as it doesn’t have a partner this row. This starts the row with each thread going under a single thread. At the end of the row I put down the first of the two threads and pick up the edge thread (a second bachelor). This sets me up for working the next row in S as an overplait row.

​Keep repeating these two rows, one in Z and the next in S and watch the pattern grow. The only challenge now is keeping an eye on the crossings and making sure that no threads jump out of place. When looking at the evolving pattern, look for sets of 3 lines in color B. 

In a previous attempt at this pattern I noticed that one of the sections didn't look like the others. On closer examination I saw that one section had only two white lines where the others had three. After determining this was a warping error I undid the entire sequence and started again with the correct warping. Glad I caught it early and not after another 20 or 30 rows!

Happy spranging, and let me know how this works for you.​ 

It’s been a busy couple months in Sprangland, with several opportunities to share and sell my work. 

With the proceeds from the sales, I purchased a domain name and upgraded to a “Professional” website. You can now find me at sprangart.com. 


Other projects keeping me busy lately are a study of how to wear sprang on your head, and the final stages of creating a year of S & Z sprang patterns for Carol James’ 2023 Sprangalong. More on those to follow.

I've found my happy place. I get to play with geometric puzzles and see the results as patterns in cloth. Initially I experimented with my fingers playing in the threads, always asking "what happens if...". As the designs became more complex I couldn't hold them in my head and finally relented and started writing the patterns down.
