I am so glad I am not the only one who finds it hard to throw away mugs! Even though I don't use all my mugs, some I don't use at all, but the sentimental value means too much to me.
I love the mug that just says 'Coffee Mug', it's simple and shows your love for coffee. I also really like the Hard Rock Cafe one, I don't have a mug but I have a Hard Rock Cafe stein which I drink water from.
