Rose Quartz Ultrasock
UltraSock is 437 yds (400 m) / 110 g of 80% SW Merino, 20% Nylon. It knits up at 28 sts x 36 rows over 10 cm (4") on 3.25 mm (US 3) needles.
UltraSock is soft enough for next to skin wear, but also machine washable and dry-able (cool water, low heat) so it's suitable for hard wearing items like children's clothing and the hats my boys attempt to wear into oblivion. I would not use this yarn for items that need more drape.
Rose Quartz has subtle muted pinks over ivory.
