My least favorite is ....hummmmm....thinking, thinkng.
Well, I think it must be the loading on the frame to quilt it. Then doing one small 4" wide band of quilting, then having to roll, then one small 4" wide band, then having to roll....OK, you get the idea. I wish I had a real longarm instead of a midarm. It would go so much faster. That is really my least favorite....oh, wait, maybe....no, right, that's it!!! :-)
But thinking about what I just said, I guess I should really be very thankful I have what I have, so, no, that can't really be my least favorite. So, I don't know what it would be. I really like all of it.
