This Raspberry Stitch Knitting Pattern creates a pretty bobble texture. This vintage texture is also known as the Trinity, Astrakhan, Cluster, Blackberry, and Bramble Stitch. The stitch is fun since it looks like little berries, especially when knitting it up in red, pink, and purple yarn colors. Get your free printable knitting pattern for both flat and in-the-round projects. My lesson includes a video tutorial for extra help with the bobble techniques.
