I'm quilting a six inch star, using a specialty template from Top Anchor Quilting Tools. These templates are so fun as they yield a great uniform shape, without marking.
I accidentally used the template upside down on the anchor post, but it works just the same, though right side up would have allowed me to line up the registration lines on the template more accurately.
I didn't put any sandpaper dots or other non-slip aid on this ruler and had no issues of slipping. Though if I had those dots or in this case "sandpaper anchors" on the template, I bet I would have noticed sooner that the template was upside down!
Aren't these cute? I haven't yet stuck these to my templates, but I suspect that the irregular, angular shape of these anchors will help grip the quilt top better than an equivalent rounded sandpaper dot.
Now I am off to get more quilting done! Gotta finish!
