Whilst looking for lace and feathers for my shoot this Sunday I came across these two excellent haberdasheries:
www.habbyworld.co.uk is incredibly cheap and postage only £2! I've ordered some lace trims.
http://www.josyrose.com/index.aspx#top has some beautiful trinkets (I especially like the feather trimmings) but beware, there is a £5 minimum spend.
Today I'm off to visit my current favourite haberdashery, Frankle Trimmings. It's enormous, I could lose hours in there just admiring the 12-foot high corridors of buttons.
