I've spent the day cursing my Horizon and need to vent. I'm so frustrated I'm about ready to sell it off. I finally said a few choice words and pulled out my Topaz. In seconds I had one side of the lining for my DD's purse done w/o the aid of a walking foot or guessing where the 1/4 seam allowance is. Press Heavy on the Sewing Advisor and I went through fusible batting and the fabric with a perfect 1/4 inch seam allowance.
What I can't figure out is why the Horizon is being such a PAIN with the 1/4 inch seam allowance. It too goes through fusible batting and the fabric with the aid of the walking foot, but finding that blankety blank, blankety blank 1/4 seam allowance is nearly impossible. This machine is amazing and is capable of so much but that 1/4 seam allowance is off.
I have to DRAW the seam allowance if I want to use the Horizon as there isn't a true marking for it.
This is the foot at 3.5 mm. The fabric isn't even on the right feed dog. If you use the seam guides etched on the plate, it's off. You may have to click on the pic to see
To find the 1/4 seam allowance at 3.5 mm I aligned my ruler to fit the horizontal line etched line of the plate and the 1/4 line on my ruler. The fabric doesn't cover the feed dog and I have to guess where to sew the 1/4 line on the purse edge.
I checked the 1/4 seam at 5.5 You can see that the true 1/4 inch is between the two etched lines. I had to put tape against the ruler and follow the tape as a guide.
What I don't get is why the Horizon doesn't work with a 1/4 seam. Both the Topaz and the Horizon have exactly a 7mm width and are the same width from one feed dog side to the other. They are the same size vertically as well. The foot for the Topaz and Horizon are basically the same width.
A couple of minutes later....Bingo! I may have the answer!! I took off the 1/4 foot of the Janome and aligned the Topaz foot under the Janome pressure foot. It doesn't fit, but that doesn't matter. I checked the center line of the foot and realized it's OFF center to the left!!!
I put the pressure foot down completely on the plate and indeed. The pressure foot is NOT centered!! Can you see how the pressure foot is over. The needle is centered, but the foot is not!!
