Assuming you don't have thousands of dollars to spend (if you do, a longarm quilting machine
with a house big enough to hold it,
are always appreciated).
But if you can't afford those, here's something almost as good: 'MagEyes, the Hands-Free Magnifier,' for around $35-$40. (No financial affiliation).
Is this an exciting look or what?
I care a lot more about how my quilts look than how I look.
To backtrack a bit: I discovered quilting in my late thirties, just around the time I was prescribed my first pair of glasses. Year after year, my vision got incrementally worse. Every year or two, I needed a stronger prescription.
But even with new glasses, after a couple of months, I still couldn't thread a needle in less than 5 progressively more frenzied minutes.
At a quilt show, a vendor was selling MagEyes, and I decided to invest.
My gosh. What a difference. I could not be a credible quilter without this thing. It allows me to thread needles in seconds, and, most important, see where I'm going when stitching, especially during machine applique and stitch-in-the-ditch, when precision placement counts.
The downsides: When I'm not using them to see closeup, I push the lens part up high, above my forehead. Eventually, I forget whether I'm wearing them. Then, when I want to see something closeup again, I start clawing at my forehead to bring down the magnifying glass section, which may or may not be there. People think I have head lice,
So release your inner watchmaker or your inner railroad model builder, or, above all, your inner Geordi La Forge....
(More info about MagEyes is on their official site, here. I notice they have come out with an even stronger one. Hmmm, I may need that one too.)
Also, let me know if you use and like a different magnifying system! There are several out there.
UPDATE: Here's a variation that will give you a forest view, no matter where you look.
