This is a fairly comfortable, good-fitting shrug made of cotton thread. Designed in such a way as to stretch a little where it needs to. No sewing needed - shrug is worked in one piece.
For the brown shrug, size 8 cotton thread was used. This can be substituted with size 10 thread or other yarn that works up to gauge.
The lavender shrug is made with Anchor size 10 cotton thread. I used the same size hook and followed the same pattern for medium size.
