Hi Beetleqeen Diva...
I have sewed for many years, mostly sewing the craft projects. I loved sewing the country bunnies and bears! Anyway, when I began to learn how to sew quilts by machine (I had always hand sewn them) my machine was not adequate. If you want to do bulky items, like the flannel quilts or flannel rag quilts...you need a good solid sewing machine. By the way, the flannel rag quilts are fun to make.
So, there are many good sewing machine brands...but my very favorite is Viking. JoAnn Fabrics usually sell Vikings...or you can go to a quilt shop and they oftentimes specialize in Vikings or other brands, such as Bernina.
At any rate, Viking has a machine called Quilt Designer...it has quilting features on it and it will do your machine quilting. I got one and I love it.
The reason I love the Viking machine is because the basic construciton of the machine is very solid..not the plastic ones that they put out today...although, I did have a Brother sewing machine that I bought from WalMart and that was a nice little machine...but it doesn't do the heavier sewing and quilting very well. Also, the Viking does not have to be oiled, as the basic machines have to be oiled. You just take it in once a year for a tune up.
I love my sewing machine...it runs like a dream and has a lot of different quilting stitches on it...
I hope this helps you. I know everyone probably has their favorite brand...some like Pepsi...some like Coke

...haha...but I have always like the Viking sewing machines....
Happy sewing....
