You've mentioned that your sister works with fondant etc. so maybe she can help you? (If she lives close to you of course...). Did you let the gelatin bloom before you dissolved it? It will have a much better binding capacity if you leave it to bloom for 10-15 minutes. Otherwise, I agree with the PP - maybe more glycerin? Oh and did you let the fondat rest for at least 6-8 hours or overnight?
