I just bought a Brother project runway and I love it, I use it for finishing pillowcases that I give to kids in hospitals.
I have made napkins with the rolled edges with my old serger.

Oooooh yes! A pieced top that was serged, and a big sheet....that would make a Wonderful duvet cover!

If you pm me when I get home I'll get the name of a book that I recently bought about serging and quilting. I think that I saw it on either Sewing with Nancy or Georgia Bonsteel and I was intrigued but havn't had time to really look at it. I'm not sure about where you live but I think here Fabric Hut sells Elna so if you can find who sells them they might be able to help you learn about you great find. I know one quilter who serges her finished tops while she's waiting for time to quilt them. It lets her know in a blink that the top is finished and protects the ends.

I have the book with DVD called Serge and Merge Quilts. Ido use my serger to piece large simple blocks. The last one I did was a quilt for my son to hug him. I used a contrasting thread with the flatlock stitch to join pieces together. After it was pieced and sandwiched I stitched inthe ditch down the center of the flatlock with another contrasting thread. I didnt find that it added too much bulk for quilting.

I've also done this pattern with a serger - it's perfect for this though I've not used it on any other quilts. I do use it still for apparel and had to break down a few years back and buy a self threading machine... the threading and tension was too much for me.

Nancy Zieman has a serger quilt video on utube. check it out. The serger seam is on top of the quilt. Looks great and think I might try one.I found a serger on Craigs list and it was a Janome brand new. The lady that owned it couldn't figure out how to use it. Got it cheap and it sews great. Just have some patience and check utube for videos for your machine and see if they have any. Or go to the machine makers web site and see if they have any informatiom that can help you.

Serger quilting
 

I use my serger for piecing quilts, strip sets and strata for strip quilts can be whipped out really quickly using a serger. You can use the serged edges on the outside as a decorative element or hide them in the inside just like traditional quilting. I serge the edges of my fabric before I pre-wash to keep raveling to a minimum. As a long-arm quilter I love it when my customers serge around the edge of their quilts to stabilize the edges- no split seams !! One thing to remember is to use a good quality thread when piecing. Not all serger threads are created equally some are very linty and fuzzy, you will not be happy with the result if you use one of these threads. I do not find extra bulk to be a problem during quilting with my long-arm. Bulk may be an issue if you hand quilt-- I don't know.

Good luck with your new serger.

I found this video on how to make a quilt using only a serger http://www.youtube.com/watch?v=sOTV-...layer_embedded
