Hobbs products are wonderful. I use them almost exclusively. Which to buy depends on so many different factors. How much loft do you want? How close/far do you want to be able to quilt? Are you hand quilting or machine quilting? Is warmth a big factor? Do you want a lot of definition in the quilting? Is this a childs quilt that needs to hold up to a lot of rough love and many washings? Is this a quilt for a senior in a nursing home that is subject to industrial laundry? Is the quilt a show quilt or a utility quilt? What is your budget, is price a big factor? As you can see there are many factors to consider. The descriptions on CT for each Hobbs batting are pretty comprehensive. Why don't you take a few moments to read the description on each batting and them make your decision.
