Okay.. this is a group of readers and I'm sure on many of your lists will be books. And, I'm no different. I know I have more books than I will probably ever have time to read (and this is just print books... don't get me started on what's on my ereader). And yet... I still buy them, especially when they are on sale. What can I say?
I have a new addiction...my kids say I need an intervention. I have started buying tumblers from Piper Lou... they are so very very handy. And, yep, I have a collection of them started and don't see that changing any time soon.
I also collect kitchen gadgets... okay, I guess that's not really a "collection" but I do like to buy them. And use them. And recipes as well. My husband tells people that I like to cook and he likes to eat, so we're a match made in heaven.
My grandmother collected salt and pepper shakers....I loved them. She had well over 300 pairs. Unfortunately, they were all at our lake house when it burned down and that was the end of that collection.
I'm trying hard to simplify my life now, though, so I'm doing my best not to get TOO many new things (other than books and Piper Lou tumblers, that is)... lol.
