Stop me if you've read this before:
Then the next row:
"k2, p3, p2tog..."
THEN you read:
"At the SAME TIME" or "Concurrently"...
...and then you throw the pattern across the room and scream a bunch of bad words that would have gotten your mouth washed out with soap, once upon a time (some of us are older knitters than others).
We knitters and crocheters have all, at one time or another, been zapped by "simultaneous instructions." A very common place for this is in a pattern where you are making a sweater or a vest with a V-neck, where you are supposed to be decreasing for the set-in sleeve and for the neck at the same time.
This is why it is always best to read a pattern from beginning to end before you start. Some crafters are of the mindset that this will only overwhelm you and make you less apt to persevere. My feeling is that if you read ahead you can be alerted to:
a) Those pesky concurrent instructions.
b) Any stitch patterns you are unfamiliar with.
c) Where you are supposed to change yarns, if applicable. In other words, do you need to buy ALL the yarn at the beginning of the project, or is the pattern going to go on and on with the "MC" for 14 inches? This may necessitate multiple trips to the yarn store, but this is only to the good...
d) Any other odd instructions. Now is probably the time to know if you are going to need to felt the item (some of us would need further instruction on this).
Now, get reading!
