That, is a fabulous quilt, love your frogs! That had to be a labor of love, hand quilting it so nice and even is an even bigger accomplishment. Nicely done. All a sewing machine would add to you work is the ability to make quilts a bit more rapidly. With your skill, you could do as I did for the first twenty years. My DD (dear daughter) bought me an inexpensive machine from Walmart, and I did all of my quilting work by buying two feet that did not come with the machine (walking foot, and 1/4” seam guide foot). Just keep your machine lint cleaned out, don’t sew over pins, hand advance through thick seems, and have fun! Welcome to this board from Oregon!
