An excellent link on making a blocked beret…
I found this great blog post on another millinery website on a blocked beret made with a straw hood. They show a technique I had not seen before of using reed that is used for basket making to hold the hood in place on the block, this is particularly important in the block shown in the post as it has folds in it. An easy way to get precise folds into a hat is to use a block with them in it. Anyway here is the link the the blocked beret post.

Thank you for this link. I had a look at it and the beret of straw blew me away. I had never thought of making them out of straw. I’ve just completed knitting a beret out of silk/cotton [band] and angora/cashmere [top] yarns.
