my friend who does professional LA has a list.. you can reserve a space when you start the quilt as soon as you know the dimensions.....if you need more time to finish the top you can drop back on the list....but when you are ready your time is 'next' so she never has quilts piling up but has continual work...... and she saves a time for charity baby quilts which she does 3 at a time on the wide frame. Ok, read this before i hit post and it is safe to say we all love her dearly!!!!!
