Do you have a specific model in mind? I can speak for the 6600 in general and my machine's quirks in particular!
1. The 9 inch open harp space is great for bulky projects.
2. The zigzag presser foot has a little button on it that is supposed to level the foot while going over large seams. For me, it has never worked. The go around? If you use the correct needle and prepare for thick seams by using a riser of some sort on the back of your presser foot to level it while sewing through and then over it, the 6600 performs well. I can't say it's spectacular and plows through anything, but it will do thick seams with a little gentle handling.
3. For home dec, I find this machine outstanding. The AccuFeed system is perfection! I have sewn dupioni silk curtains, interlined and then lined with ease and exactness. The 7 point feed dogs combined with the walking foot really do their job handling even the slickest and/or most fragile fabrics.
4. The decorative stitches are useful and fun for all sorts of projects, and many of the Janome machines have them.
5. It handles stretchy knits, spandex, lycra etc. beautifully without tension issues...
6. Overall, I'd say any Janome can do what you're asking of it. I take classes at local Janome dealer where most of us own and bring them to class. I see all model numbers in action - whether mechanical or computer and/or embroidery, and while each machine seems to have its own diva moments, all in all, we all seem to be pretty happy no matter what we're doing!
