It depends on the size of the hat. Does it have ribbing? There's a lot of give in ribbing, so it might work.
Here's how to tell: How many sts do you cast on, assuming you cast on at the bottom? Take that number and divide it by 4.75, which is how many sts per inch the pattern calls for. The result will be the number of inches around the designer wants you to end up with. Now divide the number of sts you cast on by 5, which is what you're getting. You will have fewer inches. Is the hat for you? If so, measure your head. If not, try to get the size of the head it's supposed to fit. If it isn't going to be big enough, you will need to make a new swatch with a needle the next size up.
Hmmmm interesting. There is ribbing at the beginning, then it goes to stockinette. My friend has a small head, so it might work, but what if the person had a bigger head, what changes might I need to make?
You can go to bigger needles, but you might lose the effect of the finished fabric. That's a judgement call. The other possibility is adding sts based on your gauge. How you do that depends on the design of the hat. Most hats have decrease rows towards the top. If it's a K3, K2tog, or something like that, you'll want to increase by a number divisible by the number of sts in the repeat, in the example I just gave you, you would want to increase in increments of 5 sts. If the top is in segments, you can either add a whole segment or make the segments bigger. Let me know if you have some other configuration, and I'll try to help you figure something out. -P
I've been dealing with extreme pain in my hands and arms. This is due to repetitive stress injury caused by a combination of too much mousing (my job requires long stretches at a keyboard), a bad workplace set-up (not at all ergonomic), and most distressing of all, too much knitting and crocheting, as if there really could be such a thing. I haven't been able to touch my needles for two weeks and I'm becoming very frustrated, and frankly a bit frightened. Has anyone had similar issues with hands going numb, tendons aching, and muscle fatigue? I've been to several doctors to make sure it's nothing more than over-use, and not something systemic. Other than rest (which isn't very restful!) and anti-inflammatory drugs, does anyone have any suggestions (exercises, techniques) on how to deal with this? :-(
When you do knit or crochet, take LOTS of breaks. Don't do if for more than 10 or 15 minutes at a time. Do lots of stretching exercises. If you are watching TV while knitting that can be a good marker for timing yourself. Every time there is a commercial break, it's a knitting break. I'd also say you could help with the knitting blues by playing here, but then the computer is part of your problem. So if you do that, the same time limit should apply. Get up and move around every 10 to 15 minutes and do lots of stretching exercises.
