How many times has a pattern required that a diagonal stitching line be drawn on a high number of paired pieces (squares, rectangles, etc)??? So, the correct marker must be located…..light or dark color?? Will it show?? How about those lucky stitchers whose machines have come with a built-in laser light??!!! Wouldn’t that be handy? Well, I’m here to say my most wonderful Ms Juki is now so equipped for those tasks!! 
Now, if you’re interested in a couple of testings….first, “snowballing” the corners of a 5” square……
. These little white squares wouldn’t really need a line drawn, but the laser sure helps!!!…………….
. Just line up the red marker on the diagonal and stitch!! How about a larger task……2 six inch squares needing that diagonal stitching…… 
. I don’t have to worry about a marker that shows on the dark fabric (although, I would have used the lighter fabric for that line). The laser keeps me on track….yay!!
. This small tool is mounted to Ms Juki with self-adhesive hook/loop tape (each machine has a different thread path, so you would have to check what works on yours). 
. Be sure that your thread will feed freely.
This handy addition is available at Harbor Freight for $5.99!!!! YES!!! That’s all!!!
I easily removed that mounting stand with one screw release.
If you have any questions, please, leave them in the comments and I will address them. Now…..back to stitching……………

I saw that idea on another blog recently and have it on my list of things to pick up.
I hope to give this a more thorough try in a future piecing. For now, the vintage stitchings seem to be dominating! I look forward to hearing if you try the laser idea…..hugs……
Nice! That looks really handy!
I’m really looking forward to using it!!!
Must look for one of those in the UK. Great when doing lots of diagonals. Get a perfect quarter inch seam too. Brilliant idea.
There’s so many of these tools that are for woodworking but translate perfectly to quilting…I’m always amazed!!!!
Very handy gadget there! Ms. Necchi is currently decked out with a masking tape triangle guide, lol”
Yup…..totally hear ya on that solution!
What a cool little tool 🙂
And a great $$$$$!
Thanks for sharing!
You bet. Let me know if you try it!!!!! Hugs…..
Wow, that is so cool! My next quilt has 740 tiny half square triangles and I was already dreading drawing the lines lol… Im going to definitely give this method a try, thanks for the great tip!
I hope this helps you out with this project. Hugs……
Great idea. Are the batteries replaceable?
They are. It comes with batteries so I don’t have any idea of their cost.
Wow, I’m off to get me one of those … at $5.99, that’s a bargain.
That’s what I figured. Even if I only need it once in a blue moon, the price is right.
