Lion Brand Yarn's Marble Baby Throw pattern has been my go-to pattern for quick gift items. I really like that it is quick and easy, like granny squares are, but doesn't require any piecing together. So, I've made quite a few at this point.
Another pattern I like to use is Lion Brand Yarn's Carson City Afghan, though the pattern is a lot small for my liking, so I generally double or triple it.
I've been slow to update my blog, but busy with my hooks and needles. The captions are all links to my Ravelry pages for each, if you're interested in the yarn or patterns I used.
