This is a good size to just free hand stipple. Once you get the hang of it, it's quite easy. I do crib quilts-45 x 60 on my Ellageo.
Here are 2 links to look at. The first has a good explanation and the second is her project of doing a new stippling design every day for 365 days!

Sorry I can not help with you question about software, but if you need some inspiration on free motion quilting, follow the link.<br /><br />Sounds like a pretty spezial Software you are looking for, one that thinks out of the comon framesize.<br /><br />Hope there is a solusion for this.

I can't help you Teri, I have always done by my machine, and do have something that I purchased but still in the box to that is supposed to allow me to free motion. LOL Maybe someday - Good luck, and hope you can get help with it.

You can quilt in sections, there are many books out there to explain this. Marti Michell is just one of the authers to explain this.

I don't know what type of embroidery machine that you have but my Designer SE has a stipple stitch in the sewing options. You have to hoop your project though. There is also a motif area that has a stipple stitch that will do an all over stipple for the hoop you choose. This would be the easiest option. There's no hoop for the size you are wanting so you will have to hoop several times. Maybe someone else can help with more information or your type of machine. Good luck

I have been quilting blocks at a time. I use various patterns. I hoop all layers at one time and stitch them out. It is very time consuming. I takes longer to hoop and rehoop that it does to stitch out a block. Embroidery libray has some nice designs. You are fortunate to have someone available to let you use the long arm. I'd love to have one however they are out of my price range.

Teri, you can quilt your own quilts with your normal sewing machine. You do not need to stipple. You can either shadow quilt, quilt in the ditch or cross hatch. Just remember to increase the stitch length to 3.
If you have a walking foot with your machine that also helps, but you will find that most machines do not have any trouble going though all 3 layers.

Here is a link for a free stipple design.

Teri, have you put your blocks together already and looking to quilt the layers? Or are you wanting to do all three layers at the same time, then stitching them together. The wall hanging I made, I embroidered the blocks first then sewed the sashing to connect the blocks. Once that was done,I put all three layers together and embroidered on the sashing. If you are just wanting to do your own stipple like freehand, all you do is drop your feed dogs and move all three layers together around like a stipple. Be sure to clamp your quilt rolls so it is easier to maneuver your quilt. Hope this makes sense. I am not aware of a program where you can enter the size of the finished quilt and it will stipple what the size is.(at least for a home machine) But I'm sure there is probably something out there that is like that. Hugs, Terre
