I love my serger. It is my second. My first one was a nightmare because of the threading and tension issues. Once you got it set right you sure didn't want to change it! Unfortunately you need to change it to do rolled hems, which I love. I now have a Baby Lock with the jet air threading and am IN LOVE!!! Let me tell you that I have only done one quilt on it, but scant 1/4 inch wasn't an issue with this one. I know you can measure and accurately mark where your 1/4' is to your left needle and do a good job, just haven't done it. I love it for seams on clothing and you will love it for your grandchildren's sewing. I have the Imagine and would love to get the Evolve, which has so much more for me to use - just cannot afford to do that now. You should try the serger, have the threading explained and try it. If it is too hard, it WILL be hard. Save for a Baby Lock instead. You may even want to check out a Baby Lock so you can see the difference. Good Luck
