Hat and scarf set "Stripes", 2 knitting patterns

This collection contains 2 knitting patterns. Both are easy to knit and stylish, a set of hat and scarf with funky stripes.

Basically you should be able to knit and purl. In addition, the hat is worked in rounds on a set of 5 DPNs (or circulars, if you prefer) and requires knowledge of easy decreases (knit 2 stitches together).

The hat comes in sizes child and adult medium, 40, 45cm (16, 18in) circumference; 17, 20cm (6 3/4, 8in) in length. The stitch pattern is stretchy.
Scarf: 180cm (72in) length, 14cm (5 3/4in) width. This is the size of my sample. The scarf can be worked to any size.
