I have a bit of an errata for the Lacey Trellis Spiral Poncho pattern. I had a few people make the pattern but discover that they were not ending with a number that would allow them to create the trellis portion of the poncho. I went back to the math and discovered that there was a bit of a problem. For the spiral to work, your final row definitely was a multiple of 8, but it also has to be a multiple of 6 stitches + 4.
Here is a chart of how it works:
|Starting multiple of 8||32||56||80||104||128|
|Row 3 (increase)||40||64||88||112||136|
|Row 4 (increase)||48||72||96||120||144|
|Row 5 (increase)||56||80||104||128||152|
|Row 6 (before sprial)||64||88||112||136||160|
Any of the combination in this chart will work. The original pattern was started with 80 stitches and ended with 112 before the spiral row began.
I apologize for any confusion or frustration! I hope you will share your pictures of your ponchos with me!
