Oddments are leftover bits or pieces of something larger. Those fabric scraps you're stitching together into a quilt are oddments.
You might refer to oddments as "odds and ends," or "remnants." After constructing a desk out of pine, you might use the oddments to make a wooden picture frame. And once you're finished cutting out biscuits, don't throw away the oddments of dough — you can bake those too!This noun can also be used for quirky collectibles, like the oddments your grandparents keep in their china cabinet.
