I was just doing a search in response to a request for biscornu freebies on a BB I visit and I found these two great sites, with loads of free biscornu patterns:
Aurelle – 14 designs
MissT – scroll down a bit – there are 3 pages of designs, including several biscornus
I thought these might be useful for anyone wishing to have a go at making their first biscornu, as the designs are quite small. If you need instructions on how to make one, there are links on the Tutorial Links page
