I've quilted all my quilts (both large and small) on my regular home sewing machine..either a very old Singer or my newer Bernina. If you checked the Bats in the Attic website, you have seen Paula's work....she quilts ONLY with her Bernina. I've taken 2 classes from her and she swears that SHE sees NO reason to buy a long arm. Now...that is just her opinion, however..my quilts have all looked just fine and I don't have room for a long or mid arm, so....there's no choice to be made for me.
You CAN do the same and/or even more beautiful quilting...all you have to do is try and practice! :lol:
