Mary Rose is one of 16 glorious designs in Stranded Knits, a superb technique manual and pattern collection that Ann created for Rowan Yarns. The book is available from Rowan stockists.
The cup cosy is a great little project for practising stranded colourwork, steeking, applied i-cord, and i-cord buttonholes. The book contains illustrated tutorials for all these techniques.
Please note that Felted Tweed DK is akin to a US sportweight or heavy fingering.
