Oh Jessie. I totally understand. I love to buy offering items for my altar. Every time I go overseas, I'd buy a lot of offering items that I find beautiful! Instead of putting it in a drawer and forget about it, I'd buy more offerings bowls or simply put them around the altar. My altar is so big now because I keep adding.
Some times I'd give them away to friends who want to set up an altar but don't have the means.
Found this in case you want to know more.
If it is necessary to dispose of written Dharma materials, they should be burned rather than thrown in the trash. When burning Dharma texts, it is taught to first recite a prayer or mantra, such as OM , AH, HUM . Then, you can visualize the letters of the texts (to be burned) absorbing into the AH and the AH absorbing into you, transmitting their wisdom to your mindstream. After that, as you continue to recite OM , AH, HUM , you can burn the texts.
It is recommended that photos or images of holy beings, deities, or other holy objects not be burned. Instead, they should be placed with respect in a stupa, tree, or other high, clean place. It has been suggested to put them into a small structure like a bird house and then seal the house. In this way, the holy images do not end up on the ground.
