Ok, strictly speaking, this isn't "yarn yuck"-- or at least not in my estimation. (This kind of thing will happen from time to time. Please bear with me. . .)
Still, there is something funny about a crochet cactus, isn't there? (Of course, in this case, the humor is intentional. That's ok. I take my humor where I can find it, intended or not.)
I mean, cacti are known for being sharp and prickly, yet here they are in yarn, all cuddly-soft and, frankly, adorable, with decorative beads and stitches in contrasting colors.
Though I do have a fondness for non-prickled succulents, these are the only cacti I can imagine ever having in my home. (I'm kind of afraid of the sharp ones. Ick.)
. . . Picture a larger crocheted cactus for that sunny corner of the kitchen. . . Or an elaborate one for a table centerpiece. . . Definitely a conversation-starter. (Well, unless it creates an awkward silence as your dinner guests wonder whether or not to laugh.)
