Write down what you want in a machine such as wide throat space, blanket stitch, etc... I have to have the needle down option on my machine and I love the option that i have to make the stitches wider .... it is like everything else you have to do your research and if there is a quilt show near you ...go and try out the machines ... and sometimes at the shows they give Great discounts ...!!
