My longarm has a stitch counter on it, and I just passed the 10,000,000 stitch count. 2 years, 10 million stitches. That's over 25000 yards of thread, or 14 miles of stitching.
When I bought the longarm, I had planned to use it just for my own quilts. By the time it arrived, I had 8 tops backed up, waiting to be quilted - because once I'd made the decsion to buy it, there was no way I was going to do any more quilts on my domestic machine.
But then I was convinced to do a couple of tops for friends. And then their friends. And before I knew it, the business side of things took off last October. I've done over 50 customer quilts since then. I'm still loving it, although longarming for others has drastically cut into my production of quilts. But that's ok. I'm still quilting, and instead of having to buy fabric, I'm getting paid for it :) (No, that has not stopped me buying fabric, as those who read my stash reports know).
And now, 2 years after buying the longarm, I have only 18 tops waiting to be quilted. Oh. Well, at least the original 8 are not all still waiting, although I think 4 of them are.
