Germany is very different from Croatia. As mentioned, fabrics are available there, but not the selection as in the USA. Also they are much more expensive. Currently here in the UK full priced fabrics are £10-13 per metre (about 3" more than a yard - I am just about getting used to metric), and Germany would be about the same. If it were me, I would really appreciate a "traditional American" design, as it is unlikely to be available in Germany, and she might want to make something for her son to remind him of the visit!
