Much to his dismay, my husband can't wear his beloved baseball cap at events, so I made him a dagged hood that can be rolled up into a snazzy chaperon. This type of hood/hat combo is was common during the late 14th century and throughout the 15th century.
A few months ago I made hoods for friends that were invested as Baron and Baroness of their local SCA group. Hoods are one of my favorite go-to accessories to make an outfit complete -- and warm, too!
I made 2 black linen hoods, one with a long liripipe, one without. The baronial arms are a felt applique livery badge.
My most recent project is outfitting my lord's squire brother (one tunic just won't do!). Here is the hood I just finished for him. It is a blue and deep gold linen and is reversible. He wanted an orange, and the linen I bought looked orange until I washed it... It still looks really nice though, so I hope he feels the same! This is the first hood I have embroidered - I used split stitch done in a bronze colored silk thread, a simple, but pretty detail. Don't tell him I called it pretty, though ;-)
