Joannes has Shape Flex on sale also today with free shipping. I just bought some. I normally use batting but I have heard shape flex works well. I have tried 3 time in the past to buy it and each time sold out...they always ship the stuff I ordered to just make the order amount..this time just odered the shape flex. I hate that they say they order went through and several days later..sorry sold out and no raincheck or backorders allowed.
