She has got to get some time behind a machine and see if it is something that appeals to her. Then she can think about a machine of her choosing. Classes or personal instruction would be a good start. The classes usually go over what items are essential for completing the quilt: and then proceed to sell them to the student. So she gets to try it out and have a bunch of stuff to take home and play with. I hate to say this about our chosen obsession, but a lot of people "think" they want to get into quilting but when the needle meets the fabric, find it just isn't for them. It would be better to find that out after taking a $40 class than after purchasing a $1000 machine and then, maybe, $200 worth of accessories, to go with it, and hate the whole thing. I know from personal experience that this is true. I tried to get my wife interested. I told her she could use one of my new machines and I would set up a space for her to pursue anything she wanted and I would be there to guide her and support her. Well, after making one apron she decided she wasn't interested in this whole thing and is glad to have found out before she spent a lot of money on things she wouldn't use. This is the sort of thing that can be avoided if you don't jump into something without trying it on for size first. The hobby world is rife with auspicious beginnings, and early exits.
