Just write a brief list of what you will be offering at your sale. Place an ad on Criag's List also since you do have some specific items.
Be prepared for shoppers to want to pay less than what you may think things are worth.
We just had two separate yard sales. Did great at the first one as we had more of a variety. Second one DH was nearly giving things away just so we would be able to get rid of it.
You may also want to contact a local school - home EC or even 4-H or even a senior center to donate the fabric to if it is for sewing. They could use it.
Good luck.
