How do you store your yarn? Lately it's just in shopping bags in my closet, though I'm going to bust out some space saver bags for my stash.
Do you carry it around to different rooms/ public places? I use various tote bags or purses. Nothing with Velcro. As for skeins rolling around, I don't normally have that problem, because I either pull from the center of the skein or wind it into a center pull cake. Another tactic to not have rolling yarn would be to keep it in your tote bag and just pull from that.
Any other simple problems you'd like to gripe about? (I'd love to hear them!) I have a tendency to yarn over in random spots making a perfect hole the next time I pass over. It's frustrating when I notice it a few rows up. Then I have to tink back to get it out. I'm sure there's a way to fix it, but I haven't figured that out yet.
And lastly, this doesn't have to be reserved for knitting. If you hate something about a task in your morning routine, or wish some product existed.... let me know! Nothing I can think of specifically, just wish my kids listened and followed directions better.
