Fabulous 2 ply Debbie Bliss yarn, comprising 100% extra fine merino wool superwash. Rialto Lace is a soft, beautiful, fine yarn that gives drape while lending clarity to the most delicate of stitches including those featured in her Rialto Lace pattern book. Just perfect for the gossamer like knits that lace yarns create. It is the perfect combination of finer weight with a fibre we love.
