I have a few sentimental items, but I will give a shoutout to an honorable mention of these multicoloured twist-ties that I wrapped up into a heart-shape from my grandfather's old garden from before he died and my grandma moved from that house..
It always reminds me of my grandfather, and that house where I would have my secret "lookout" which wasn't really a secret.. it was just beside the garage in the garden on a higher piece of land.. and enjoying picking veggies, fruits, and watching my grandfather pick walnuts and other things from the tree.
Those twist-ties are valuable to me. It is one of the things I keep in my safe.
I also have a few sentimental drawings.. actually I have quite a few sentimental things.. I am quite sappy.
