I'll take a look into all three of the Dollar Store type businesses we have here in 29 Palms. Hopefully one of those will have something at a reasonable price. Of course, I really don't know what is reasonable. I think I am just too old, and remember when things were a lot cheaper.
I watched a couple of YouTube videos on the waling foot. Got mine installed.
I took a couple of 4 inch fabric squares with a piece of batting between and did a couple of lines of stitches. I just stopped, lifted the foot, move the fabric 90 degrees, and then moved an inch, then did the same thing until I got those three lines. Worked perfectly
Not sure what thread colour to use. I switched to a stone colour for the test. I guess this colour is fairly neutral to most of the colours in my quilt. Unless someone has a better alternative, I will go with this colour.
