I used to live in Budapest. If you are there during a festival time, there is a good chance that one of the booths will be selling the kekfesto blue fabric that is very traditional Hungarian. The booth will have a "fat meter" packs of the fabric as well as yardage (except they will sell by meters, one meter being 39 inches). Surprisingly, the cost of those fat meter packs is about comparable to what we pay for fabric here in the US. North of Budapest, about a 45 minute to one hour train ride is a lovely village, Szentendre. In the "old village center" is a small shop that sells these fabrics, and that would be a lovely day trip for you. If you are interested, private message me and I will give you some details.
