Lisa, I have the same machine! right now I have two quilts going , both are wonky log cabins and I am just quilting square after square after..... well you get the point one measures 48x60 and the other is 50x62
I have done several baby blankets on my machine most are about 40x48 or so!
How large are you wanting to go with the quilt?
I think now that I have gotten use to managing a "larger" (than just a baby blanket) quilt I could even go bigger on my machine! Its all in learning where to put the excess fabric that you don't need in the machine! and knowing what fabric has to be where for it to work and what way you can turn the quilt to get closest to the part you are working on and have the least amount of quilt bunched up in the throat space!
