This crochet pattern is for a men's hoodie that features two striking crochet techniques: keystone effect and linen stitch. The keystone effect is created using a mosaic technique with long double crochet stitches. The linen stitch sections use two colors to create thin vertical stripes. All techniques are explained and stitch counts are calculated according to size. The design includes a large hood with a drawstring around the front. The pattern includes options for size adjustment and design, whether you want to go sleeveless or include the front pocket.
