I love Leah's site (and I'm not only saying that cos she's in the room! LOL) - I used to find some of the designs intimidating when I first stared FMQ (especially those requiring a lot of back tracking) but now, with lots of practice under my belt, I can manage most of them - and yes I use them on large quilts or use her ideas as jumping off points to create my own designs. Perhaps it would be fairer to describe her designs as 'aspirational' rather than intimidating - I believe we can ALL get there with PRACTICE. :D
