Do you know approximately the thickness of the ostrich hides you have, and are they supple or stiff? That info would be somewhat necessary to give you any truly good suggestions.
If it is thinner and on the supple side, small wallets/clutches/coin purses are an awesome use of ostrich. If you have a good cowhide in maybe 6-7 oz to line it with it would also make a beautiful belt. Inlays in other items are a good use also (holsters/knife sheathes/etc.)
If it is relatively stiff and/or thicker, I'm not sure what I would attempt with it.
Also, what condition is it in? In storage since '02 would have me concerned that it is very dried out and brittle, but I could definitely be wrong. I built a holster for a friend out of 12oz saddle skirting that he had in his garage for about 15 years, and after a good couple coats of neatsfoot it worked fairly well.
