Here's a couple of creative ideas, Janet:

You can use this for the base/legs and add a shelf.

You can use them for table legs and bench legs.

I have a ton left over too. I plan on making small outdoor furniture like plant stands and side tables with mine.

If a deck spindle is what I think it is,you could use them as legs for a table, chair(s), cut them in half lengthwise for framing photos, (as long as used in outside), & put sea shells, sea moss, fish netting, etc , under glass frame for wall hanging or as a table top. Or even a BBQ themed arrangement, like a picnic tablecloth, BBQ utensils, (cut in half 1st) condiment bottles, plastic spice bottles w/labels, BBQ pit holders, etc..

Use as legs for items. or surround a Pot with them to match in with your deck decor.

Frame a mirror etc.
