"Never give up on your horse because your horse would never give up on you." This is one of my favorite quotes, recently I had an accident with my favorite horse and it shook me a little, but i would never give up on her she's my baby!
I love this idea. An envelope guest book. You just take a store-bought scrapbook/album and glue envelopes into it. Lay out colored pieces of paper for guests to jot notes down on, and then they can place them in the envelopes.
