These are the cute 25g skeins of Alegria Grande from Manos del Uruguay, which is the bulky sister of Alegria. This incredibly soft Fair Trade yarn with its wonderful twisting gives a wonderfully clear stitch pattern. The finished knitwear has an excellent elasticity and due to the light weight they remain shape-retaining. This "Grande" version creates quick, satisfactory results, even for knitting novices.
