Slipper Sole Experiment

How to prevent people from breaking their necks wearing splippery slippers? I did a little garter stitch swatch (approx. 1.5" square) in the same yarn as the slippers and added some puff paint stripes and dots to it. Maybe a series of dashes will make the most sense in the end. I think a long stripe will just crack when the sole is stretched. To apply the stripes I just used the bottle's applicator, but for the dots I also poked at them a bit with a toothpick.

The directions say it should be dry in 24 hours, so we'll see tomorrow how well it adheres to the yarn. And now I must wait. Humph.

Update - after about 3 hours, some of the paint appears translucent instead of white. Hmmm.
