Once you try Debbie Bliss yarn it is hard to go back to any other. The quality is wonderful, the colours exceptional, and her patterns are simply exceptional. Rialto 4ply is a super smooth 4ply extra fine merino which knits up evenly and the finish is what any knitter dreams of.
It is also spun from superwash wool,  which allows the finished garment to be machine washed.
Knits up to a standard 4ply pattern but remember to check your tension!
