This first tiny knitted one is for a newborn and fits 14 - 15 inches. It is nice and stretchy and you have all the benefits of real wool - warmth and moisture wicking.
This next one is made of the same wool but fits a slightly bigger head and can be worn with a folded brim or not. It fits 17 - 19 inches and 
could even stretch a little farther.
This is the last of my ear flap hats (I've got to make more of them!). This one is crocheted with a lovely German yarn that is a wool blend so it is very soft and didn't need to be lined. Although it will still need to be hand-washed in cool water and laid flat to dry. It fits a 22 - 23 inch head.
This pretty lacy hat is 100% acrylic. It is very soft but not as warm as wool. To preserve the texture of the hat, it should still be washed by hand and laid flat to dry. It fits a 22.5 - 23.5 inch head.
This light blue hat has a lovely texture that is impossible to capture in a photo. The yarn is a mixture of light blue and white. It is considered a 'light denim'. It is 100% acrylic and soooooo soft! It is crocheted in a variety of stitches and has a picot edge. It fits 22.5 - 23.5 inches.
This child's hat is made from a similar yarn to those in the previous post. I found it in a discontinued bin at the yarn store, unfortunately as everything I made with it was very popular and I can't get any more. This is the last one left. It is acrylic with wool trim so it still needs to be washed by hand and laid flat to dry. It fits a 19 - 20 inch head.
This next hat is very fun. The plain pink yarn is wool and the fun, blobby stuff is an wool/mohair blend. It can be pulled low to the eyes or it can be worn high on the forehead which creates a little peak as
it is in this first picture, here. Not only fun, it is beautiful and warm. Double click on the smaller pictures to get a view of the top and the texture. As you can see it fits me comfortably which means it is for a BIG head. It fits 23 - 24 inches.
And here is another fun hat. It is 100% wool and crocheted from Noro wool which is a Japanese brand. It is one of my favourites to work with. I just love the colours. This one is lined with light grey micro fleece to keep the wool from itching. Another large hat, it fits 22.5 - 23.5 inches.
This child's hat is crocheted from my ultimate favourite yarn - Lopi wool from Iceland. I love it so much that I bought Icelandic sheep last summer so I can have some of my very own. A friend of mine is spinning my first batch of fleece right now. Lopi wool has an extra long fibre which makes it lustrous. You can see the sheen even in this picture. It is very warm and lined with micro fleece for comfort. It fits 21 - 22 inches.
in it as well.
The yarn for this hat is a medley of pinks from pale blossom pink to dark pink. It has been a very popular yarn and this is the last hat I have made from it. It fits about a 20" head. You can fold up the brim or wear it down.
These next two hats are made from the same yarn but are slightly different shapes. The yarn is a mix of cream, dark and light blue, dark pink, green and gold.
This next one is longer and has a brim that can either be worn folded up or worn down. It fits 22.5 - 23.5 inch head.
This is my most popular design. I guess it has become a bit of a 'signature' design. It is single crochet with a picot edge. The trim is wool and alpaca wool so it still has to be washed by hand and laid flat to dry.
This little elfish hat is of the same wool blend. It is hard to capture the shade of orange on camera. It would be considered a 'burnt' orange. It also has wool trim with a picot edge and is done in single crochet.
This hat is made of the same yarn as the first only the trim is also a washable wool so this hat is entirely machine washable although I would recommend laying flat to dry. Please double click on the small image to get an idea of the texture of the hat. This one has a plain edge. But if you really wanted a picot edge, it would be no trouble to add it at no extra charge.
And this hat is the made of the same yarn as the previous hat with wool trim so not as washable. It has a single crochet band with a half-double crochet top. It is a very large hat - I have a big head and it is loose on mine.
This is the first hat that I knit following Elizabeth Zimmerman's instructions on a video from the library from her PBS series. I highly recommend the video and I had so much 
fun! I love a challenge! Here is a close up of the fair isle design. Double click on the image to get the full effect.
And here is its sister hat. This one is crocheted out of the same Patons Shetland chunky in counterpane stitch with a picot edge
This wee hat is %100 wool and fits about 40 cm (16"). But it is stretchy so it could fit a bit smaller and a bit bigger. This was my knitting project in Mexico and I was pleased to see that I was not the only one who brought my knitting to the beach...
And here is the crocheted hat - much smaller yet using the same amount of wool. 
Please double click on the images to get the full effect of the texture and the ruffled brim.
This warm adult sized Hippie Hat is made from 100% lopie wool (Icelandic sheeps wool) with 100% wool and a wool blend trim. It fits 22 - 23.5" (56 - 60cm). It is lined for comfort with grey micro fleece.
This hat is the first one that I ever crocheted with ear flaps. Perfect for skiing or playing outside! This hat is 100% wool with angora blend trim and is lined with micro fleece for comfort. It fits 22.5" - 23.5".
I wish I could better capture the detail on this, my newest favourite hat! I crocheted it this summer with 
the softest merino wool I have ever worked with (Mission Falls). I was inspired by Debbie Stoller's book, "Happy Hooker" which made a scarf out of these flowers.... I made them into a hat! The background is a dark plum purple and the flowers are in a red, brown, purple and green - not quite as bright as the flash makes it look! You can find more about mission falls wool here. The colours on this hat are their poppy, nectar, damson and pistachio... and I have a bunch more of their colours for another hat, too! But now the details...
This first hat is made from Red Heart's TLC Amore and is 80% acrylic and 20% nylon. I love the colours and it is soooo soft! Hey and I couldn't resist making a daisy and sewing it on. It fits a 48 cm (19") head.
