Check the library for Sally Melville's garter stitch knitting book. She has a very unusual jacket. There's also the Einstein coat, all in garter stitch, and yes it takes lots of yarn.
You can also use a short circular needle instead of a cable needle. I find this much easier as the cable holds the stitches and the needles are not in the way of your work.
A cautionary tale about needle/stitch gauges. The majority of gauges are a combination of US and metric sizes. US size is approximate, metric is accurate. This is why many of our needles, when inserted into gauges by Boye, Susan Bates and other US makers, measure differently than when inserted into metric gauges such as Addi. Manufacturers really recommend having a gauge for each brand of needle you have.
When you talk about knitting backwards are you referring to not turning your work to purl? If this is the case then this method works well with entrelac for the most part as you are just knitting and purling.
Try the Clover Armour from JoAnn's with cushioned handles. But everything depends on how you hold the hook. Some of us hold the hook as we hold a pencil, others hold a hook as a child holds flatware when he's learning to eat. After carpal tunnel surgery I changed my hold to "overhand", similar to a child holding a spoon.
When using a needle as a lifeline, use a smaller size. Makes for picking up those legs much easier. Then you can knit off the smaller needle.
Cheryl, there are many versions of selvedge edging. Go to search on this site and read what we have said. The one I use the most is as follows, though it does take practice, "cuz yah gotta remember."
SLIP the first stitch purlwise THRU the back loop, slip the yarn to the back between the needles and knit the next stitch OR keep the yarn in front and purl the next stitch, depending on the pattern
KNIT through the back loop the last stitch of the row no matter what the second to the last stitch is.
I do this on every row no matter if I am knitting or purling.
This technique provides a crocheted looking edge.
What are you trying to knit? This will help us help you by understanding what you are trying to accomplish. Stockinet curls, period. It's the nature of the beast. CherylBrunette.com explains very well why this happens.
See if you can locate the Addi square #412-0 which measures a 4x4 square. This works very well for isolating an entire section of knitting.
Just consider the source and ignore it.
My father's memorable comment when asked how happy he was that he was gaining another son. "I'm not gaining another son. I'm getting my car back."
If you want the colors to show, find a pattern that has more stockinette stitches vs. yarnovers and lots of holes. With the yarn name check to see what knitters on Ravelry have made.
Cotton yarn has a tendency to stretch. The larger the item, the more the stretch.
Go to search on this site, type in Baby Surprise Jacket or BSJ, and read what we have said about this sweater. Try to locate the number line chart which tells you how many stitches you need for each row. Google civilbitch.com.blogspot baby surprise jacket decreases. This is the chart I used for making the jacket. I also noticed an update so check this out also. There is also a youtube video that explains what happens when you change yarns and needle sizes.
