As many others on the board, I am making a goal this year to finish 12 UFOs and I have over 30. I will not buy any new material and will make many scrappy quilts from all my leftovers.if cost is an important factor in your hobby it is wise to only work on one project at a time and most shops will let you buy fabric on lay-a-way so if you must do a project with that material you absolutly must have it is a good way to do it. I have selected a pattern, gotten the material, backing and batting and put it on this payment plan and several months later I have a complete quilt paid for and to enjoy making. It can be a very expensive hobby. Also if you like scrap quilts most people are willing to give scraps way and all you have to buy is the backing and batting.
peace
