I hope it works out well for you!
Try to take photos of the object you want to sell in front of a neutral background to show the object clearly without any background distraction.
And as Sarah pointed out, be sure to point out any flaws - you can even show a picture of the flaw so people will know exactly what they're getting. If your description & photos show the objects as accurately as possible, you're less likely to have problems with buyers.
For items that it would be hard to tell the actual size from a photo, it can help to photograph them with a ruler, and/or state the item's dimensions.
You can use the Ebay photo hosting service, or you can use an outside service such as Photobucket.
Try to list all the 'keywords' that apply to an item in the description, so your item will show up in more searches. (But don't 'spam' your description with words that don't really apply just to get it to show up in searches - that's not allowed). Just try to think of alternate names for the object that other people might call it (for ex: some people might call a hairstick a hair pin or a hair pick or hair jewelry).
Before listing an item, weigh it complete with packaging so you can give bidders an accurate estimate of postage costs - Ebay has tools to help you figure the postage cost once you know the shipping weight and dimensions.
There are forums on Ebay to help sellers and buyers with questions - you might want to go and look at them to get more advice about selling and shipping, and to read about the experiences other sellers have had.
