What a wonderful person you are.....thank you, for passing on the craft of sewing/quilting. Since she is an expert at sewing on your Designer SE, don't go for the "child" machines, look for the best buy you can for the $400. Don't buy at Walmart. You will not get service if needed. A gently used Janome, or a new one in your price range would be great. Look for quilting featuress, since she likes to quilt. Ken sewing has the Janome 8077, 30 stitches, plus bonus kit of Quilters package on sale for $349. They along have the Janome hd3000 for $399. Either case, no tax. Free shipping. Talk to Ken about which one he feels is best. Great folks, .....I do not work for them. Best wishes...let us know what you choose.
