I had one ball of Highland Alpaca Fino left from another project, it is nice yarn but it has limitations in that it is soft, breakable and slightly stretchy. So not good for gloves. I settled on a slip stitch beret by Isolda Teague. It's actually knitted flat on two needles, using short rows to shape it. In the photo above you can see the provisional cast on, which is undone afterwards, with the two edges cast off together at the end to join it up.
Here it is after finishing - the casting off leaves a hole in the middle which you have to join by running yarn round it and pulling it up. It's quite small once finished.
After blocking on a dinner plate it is much bigger, though you can see the shape of the plate in it! I think that will wear off in time. I did use bigger needles than recommended due to the character of the yarn - I used 5mm and judging by the comments of others who found it small, this was a good idea. But you can also put in an extra repeat or two of the pattern if you find it small, just wrap it round your head before casting off to check.
Here's a close-up of the pattern, it is very pretty and a very clever patter, but does take a bit of concentration!
