I have been thinking about this too, I am thinking about using something in the bottom for weight and filling it the rest of the way up with steel wool because I have been reading that this will keep the pins sharp.I have also read to buy bird grit in the pet isle at places like walmart I did pick up some of this at wal mart ,it comes in a box about the size of a mac and cheese box ( I had trouble finding it cause I was looking for a bag).It was around a buck I think. Remember the old tomato pincushions that had a small strawberry attached with to the larger pin cushion to sharpen needles ? They had some type of grit in them . You know back in past times pincushions were filled with hair ! My grandma actually had a hair jar that you placed the hair in after you combed your hair, it was specially made for this purpose. She was proud of this hand painted little container , she used to tell me that the " rich ladies had them in the olden days "so it made her feel fancy when she looked at it lol
( They were actually called hair receivers for those interested in fun old facts)I know way off topic but a fun fact that women used to use hair.
