Soft, strong, and washable, this 4-ply yarn is our workhorse! The plies help resist pilling and washability makes it fantastic for frequently-worn garments and kid clothes. 

Be sure to get enough yarn to complete your project since each bag is a different dye lot, and skeins may vary from bag to bag. Skeins may vary one from the other even within the same bag. To ensure random color distribution, work from two balls of yarn at once, alternating a few rows from each ball.

I love the colors. They flow so well

Love Rios!!

I have been using Malabrigo Rios for years and I continue to love it!! It is a pleasure to use and is also a good yarn for a good price! The colors are wonderful and don't fade. When making something (sweater, scarf, cowl, whatever - I have done them all with Rios - sometimes you should alternate skeins of the same color since the darkness/lightness can vary, but that is a small price to pay for a beautiful yarn!!


Perfect yarn for my sweater. Rich colors and a joy to knit.
