"I just wanted to say how much I enjoyed the pattern cutting course I attended last weekend.  This weekend just gone I made a pair of trousers using the block that we produced and it's the first thing I have ever made that doesn't feel home made and actually fits perfectly!  It has rekindled my enthusiasm for sewing and I can't wait to make my next well fitting garment.  Could you please pass on my thanks to Alice for making sewing enjoyable again and for turning on so many lightbulbs in my brain!"
