I already posted what yarn I used for my first one, but for the second, I used the same Red Heart Symphony and Target flag yarn, but combined it with some lime Target cotton yarn I bought in one of their yarn kits. It's a bit washed out in the pic because of my flash; it's not yellow, it's a nice pretty lime green. I'm now noticing, however, that I need to dust LOL. Boy the flash really picked up the dust that I can't see IRL.
And here is a picture of Patches displaying what I made for my Dad (and will be finishing another for MIL once Jason is around to help me sew):
It's a microwaveable rice pack. The outside is knit and felted, and then Jason sewed up a little muslin pouch which I filled with rice and lavender buds. I used some Hemp/Wool yarn I had in the stash and it felted up beautifully! I really like the texture it ended up with.
