I made this to wear for a friend's wedding, it knits up surprisingly quickly given that it's laceweight. The yarn is Dyeforyarn's Lace / Tussah Silk, available on Etsy. This is a really special laceweight yarn available in a huge range of colours. You can buy this pattern on Ravelry or on Etsy.
The second pattern is a lacy hat pattern, perfect for Autumn.
The hat pictured is made with my own handspun, handdyed Bluefaced Leicester yarn, but I’ve suggested two commercially available yarns that would be fine too: Knit Picks Palette and Rowan Pure Wool 4-ply. If you want me to spin you up some yarn for this pattern though, just let me know! Again you can buy this pattern on Ravelry and Etsy. Thanks for looking!
