Why not knit yourself a cool cotton top for the summer.
The Urth Yarns Boat Neck Tee Top pattern is available in 9 sizes (30" to 58" bust) and 3 colourways. Prices from £24 to £72. You will receive a free pattern when you buy the yarn for the top. Cotton isn't a 'stretchy' yarn like wool so buy a size up if you want a loose fit.
Needles required: 4.5mm straights or circulars and 4mm DPNs to join the side seams using an I-cord
