Joann's fabric is great for the charity quilt work I do. OR if I'm trying something new and don't want to pay an arm and a leg for the fabric.
I do like the LQS better for their personalized attention (AHH CUSTOMER SERVICE), their top notch cutting skills and just all around ambience. Their in shop specials, the great deals they spring on customers, etc. BUT unfortunately, those wonderful things do not make charity quilts.
Joann's is great for someone who already possess the quilting skills, knowledge about fabric, etc. When I'm in doubt I go to the LQS.
Our shop is nice but it's all crammed in a small space.
I did purchase on Saturday with my 50% off coupon 10 yards of warm and natural batting for $55! It is 90" wide which means I can get a lot of quilts out of one yard!
Have a great day
