Perfect Piecing seam guide
 

is anyone using 'Perfect Piecing Seam Guide' for scant 1/4 inch sewing?
I am struggling to have good scant 1/4 inch seam on my Juki.

One way to achieve a scant 1/4 inch seam is to move your needle one position to the right.

I simply use one of my rulers that has thin lines on it. Would work just as well. Here is a link to it on Amazon:

I place my ruler under the presser foot in a similar manner, lower the needle so it is just to the right of the 1/4" line on my ruler, lower the presser foot to hold the ruler in place, make sure the ruler is running straight from front to back, and use the hard right edge to position an adhesive seam guide in place for my piecing. My favorite is this Dritz product:

but it may no longer be available. If not, I will go back to my trusty moleskin. (Moleskin is an adhesive foam product available in the foot section of any pharmacy, Target, Walmart, etc.). This creates a solid guide against which I can butt my strips as I sew.

sadly, not all machines have this feature.

Are you using the markings on the seam plate as a guide? I bought a 1/4" foot with the metal edge guide for my Juki on ebay. I find that easier to have a more consistent seam.

I use it. I use it to mark my machines throat plate and to check the accuracy of my 1/4 inch feet with the fabric guides. I accidentally threw my first one away by not hanging it up when I was finished with it. When I realized it was gone the next time I wanted to double check a measurement I ordered another one. I love the little thing!

Even more sadly, even when the needle is all the way to the right, my machine doesn't give me a true scant 1/4 inch seam...

I put down blue painters tape making about 5 layers of the tape as a guide. Keeping trying different methods until you find the one that works best for you !

I bought one at Walmart. It worked to find the 1/4 inch but I didn't like the look of all that tape on my machine though.

I have one and really like it!
