I can't seem to find any website in the UK that stocks these fab patterns!
I have two of her books - U Sew and the Stretch sewing one, that has patterns in the back of them and I got them from Amazon. I haven't used the Stretch one yet - but I have made the pants from the U Sew book and they worked out well. Amzzon had free postage recently, not sure if it is still on offer??
You can get the patterns here: http://www.sewingpatterns.com/search.php
They quite regularly have patterns for $2.99 so even with postage it might work out economical for you (or you could download them).
Thanks Debbie! That is super helpful and its the cheapest shipping cost I've seen! Yay!! x
