How big is your table topper? And what are your future plans for projects? You could get a small one for this project and then find you need a bigger one for another project.
I have 4 big oval hoops (30")and one smaller (24").
You can always baste extra fabric on the sides of your project to hold it in the hoop.
Just wanna add, Way to Go!! for trying hand quilting, I love it. I hope you will too.
