I was going to add for those of you near a Costco, they have king, queen and twin sized microfiber blankets selling between $17 and $22. These would make marvelous quilt backs. I bought one (king) to use on my bed and the quality is wonderful. The sizing is generous, as well.

Love the bright color and soft look.

Is it stretchy? If so, you may want to pin, or baste much closer than usual.

I would use it for sure! I was given a hint that will help with minky, use 505 or something similar to spray the minky so that the fabric does not slip around. Also pin alot! with these two hints I think using minky will be a lot more fun experience!

If its minky it will be fine for backing.

It will not shrink.

Use batting. It will have a better drape.<object type="cosymantecnisbfw" cotype="cs" id="SILOBFWOBJECTID" style="width: 0px; height: 0px; display: block;"></object>

I use minky and ultra cuddle all the time for backs of quilts. I also use batting. MN is cold in winter, but my dad uses the throw I made him year round. I would also recommend basting spray. as it can be a challenge for fmq. If you fmq, you'll also notice a lot more drag than with a cotton back. It's not impossible, just something to be aware of. as you will want to take frequent breaks in order to rest your arms and shoulders.

I was wondering the same thing, only with Minky on the back. Would that work on a long arm?

I spoke to this issue in post #15 in this thread ... you might want to take a look!

The same thing happened to me and I don't think I'll ever buy a microfiber thing again.

I use minky in my quilt backs and it quilts fine. However I find the 505 doesn't work real good in the minky so I have to pin it some too. Or tie it. I have quilts I tied way before machine quilting came to be and they are still going. I gave heard that tieing is on the comeback.
