Nothing annoys me more than reading a garment pattern that tells you to increase or decrease evenly across a row or round of stitches, and lets you figure out how to do it. In the past I dug out my books of how to's, grabbed a pencil and paper and followed along with a complicated formula. The sample in the how to book of course works out evenly, which for some reason mine don't. Well, a couple months ago, while looking for APPS for my new I-Touch, I found an APP that will forever solve the issue of increase/decrease evenly on a row on knitting. The APP is called "Knit Evenly" and can be downloaded onto an I-Phone, I-Touch, or I-Pad for only $1.99. Its easy to use by plugging in the number of stitches on the needle and the number of stitches to be increased or decreased. Then you select "Flat" or "Round" , touch the "Calculate" tab, and instantly you have before your eyes 2 options:
option 1 is simpler and easier to remember and option 2 is more evenly distributed. Both options have a "guide me" that takes you step by step through the entire sequence to follow on your row of knitting.
I highly recommend this APP.
