The Pin Check Pattern is a slip-stitch pattern almost identical to the Waffle Check Pattern. In fact, the only difference between the two patterns is rows one and five.
However, this tiny difference creates quite a difference between the two patterns’ texture.
Furthermore, the Waffle Check Pattern has quite a nubbly look and feel. Conversely, this Pin Check Patten is mainly a stockinette stitch pattern with a few “nubbles” interspersed.
So, just like the Waffle Check Pattern, this color-change stitch pattern is knitted over 8 rows. In addition, you can easily create a variation. You can do this by just repeating rows 1-4.
In fact, this slight change will cause the checks to be aligned vertically above one another. Consequently, this is opposed to the main stitch pattern where the checks are alternated.
In addition, if you would like to try out knitting the Waffle Check Pattern as well, you can find it here: Waffle Check Pattern.
As this is a color-change, slip-stitch pattern, you will not have any of the issues that can arise when knitting stranded or fair isle knitting.
Actually, you only knit with one color for two rows. You then change the color and knit for another to rows – super easy!
Finally, this way of knitting with color is typical for mosaic knitting. Meanwhile, we have a great article on the topic which you can find here: All You Need to Know About Mosaic Knitting.
