First, I wanted to go over "Multiple of x stitches, plus x". This isn't an abbreviation, however it is frequently seen with stitch patterns.
For example, Bee Stitch is worked over a Multiple of 2 stitches, Plus 1. So how many stitches does this mean to cast on? A multiple of 2 = 2, 4, 6, 8, 10, etc. Let's say you cast on 30 stitches; you would then need to cast on 1 more stitch, making your total stich number 31.
If your stitch pattern calls for a Multiple of 9 Plus 3, you would cast on 9, 18, 27, 36, etc., Plus 3 more stitches. So, if you cast on 27 stitches, you would cast on 3 more for a total of 30 stitches.
These are standard abbreviations that you will see within most patterns. However, sometimes you may see something out of the ordinary; your pattern should provide a key for what each abbreviation used stands for. This is not a complete list by any means. I will continue to add to this as I come across relevant information.
