Like a lot of knitters, we have a lot of different swatch gauge tools in our possession. It would take a lot for us to take a look, or even try another swatch gauge.
Here's why we love this one from Ackerworks.
It’s transparent. You can see the stitches beside and below the stitches you are counting in the window. This enables you to confidently know when you’ve got a half stitch, or even a quarter stitch, in the window.
It doesn’t slip. The grippy teeth on the four corners keep it it place. It will not slip a half stitch while you’re counting.
It lets you count rows and stitches, inches and centimeters, at the same time, thanks to the 4-inch cross-shaped window design. One side of each arm of the cross is marked in whole inch increments, with 1/4″ marks between. The opposite side is marked in whole centimeter increments. No more doubling a 2-inch stitch count to approximate the 4-inch gauge.
It’s sturdy. It fits in your tool bag, and will keep its shape.
