I love Tutto rolling cases - nothing else compares or comes close, especially with arthritis and a bad back!
I have two - one for my Sewing Machine and one for my Embroidery Machine. For size, I went with Tutto's website recommendations for my machines, and they fit perfectly. By the way, Wal-Mart.com sometimes has them and my local sewing machine store matched the low price. And the 2nd one I bought was for Joannes using a 50% off with free shipping coupon.
