I knit and crochet, and these are some great yarns.
Love this yarn. I drop ship it from the UK though
James C. Brett Marble Chunky Yarn
This is great to make teddy bears, shawls, scarves, sweaters. The color has subtle variations
Homespun® Yarn - Lion Brand Yarn
This was a challenge to work with, but it is very beautiful.
Sirdar Jewelspun Aran, 200g
This is great for making toys, amigurami, plushies, and character hats.
Red Heart
I mostly use their worsted weight and this is Michael's Crafts store brand. They price competitive and it's easy to work with. The colors are on par with name brand as well.
Loops & Threads
Same wonderful colors as the chunky, but this is much thinner. Good for socks and things needing a more delicate thread.
Marble DK - The Yarn Patch
This is fairly easy to work with. The sparkle is metallic thread running through it. Wonderful for anyone wanting glitter or sparkly quality to the item.
