I have a favorite type of hat to make and I've made several. I've often considered publishing a pattern and charging you for it, but I've come to a different conclusion after thinking long and hard about it.
I'm going to put it here for you for free. Why not? It's not especially complex or even that unique and special. But it's a good pattern if you like this kind of hat.
This is the kind of hat that guys might like, especially guys like my brother who have problems keeping their heads warm as the hair gets thinner. I like it because it looks good on me.
YARN: This hat can be made with any size yarn. I'm going to give you the basics and you can easily translate them to the size and type of yarn you're using. I suggest that you use a yarn that doesn't have a lot of drape and isn't too fluffy. Those will probably droop unattractively if you go there.
GAUGE: For yarns, like cotton, that tend to stretch out and stay that way I would recommend a tighter gauge. For yarns, like wool, that tend to "snap back" after being stretched, you can use a firm gauge. Don't go too loose or your hat will get droopy again.
MEASUREMENTS: Please measure the head that the hat is for before you begin. You need to know how big around the head is and the approximate height from the top of the ear to the top of the head. If you have a tape measure, that will work well. If not, take a piece of yarn and use it to measure, holding the length on the yarn with your finger while you measure how long it is on a ruler or yard stick. Take the head circumference and use it to figure out the diameter of the hat by using this formula: diameter=circumference/3.14 (pi). Take the number you got when you measured how big around the head is (circumference) and divide it by 3.14 or pi. That will give you the diameter of your hat.
Now that you have your measurements, this is what you need to do to make your hat.
Make a Magic Loop OR ch 4 and join with a sl st to form a ring.
Rnd 1: Sc 6 in the ring just formed. Use a stitch marker to mark the last stitch. Work in a spiral from now on and move your stitch marker from round to round to keep track of where your round ends and the new one begins.
Rnd 2: Sc 2 in each st around. (12 sts)
Rnd 3: [Sc 1, sc 2 in next st] 6 times. (18 sts)
Rnd 4: [Sc 2, sc 2 in next st] 6 times. (24 sts)
Rnd 5: [Sc 3, sc 2 in next st] 6 times. (30 sts)
Rnd 6: [Sc 4, sc 2 in next st] 6 times. (36 sts)
Continue working in this way, increasing 6 times every round until you have a fairly flat circle that has the diameter you determined from your measurements. It will probably look a bit like a hexagon because that's what you are actually making. I'm not bothered by this because it's hardly noticeable once you start working the sides. However, if you are, stagger your increases so that they occur in different places along the round.
Edge: BPsc around.
BL stands for back post and it means that instead of working your sc in the top of the stitch you're working around the post of the stitch from the back. This makes the edge nice and sharp for the turn to work the sides. When the end of the round meets up with the beginning it will be a little offset, but that doesn't bother me and I just use it to see where the back of my hat is.
Rnd 1: Decrease by sc2tog 6 times at even intervals. This also sharpens the edge and actually makes the hat fit better.
All Rnds after: Sc in every st around.
Continue until the height of your hat matches your measurements. It should fit in such a way that it has to stretch just a little bit to go on. This makes it comfortable and secure. If you're using a yarn that stretches out and doesn't snap back you may need to do one more row of decreases to compensate for that.
That's the basic template. Now you can come up with all sorts of ways to have fun with it.
• You can replace the single crochet on the sides with other stitches or stitch patterns.
• It's sometimes nice to add an extra finish to the bottom edge such as a crab stitch.
• You can also make one with an exaggerated height so that the top flops over to the side.
Have fun with it!
