If you put a picture of the batiks up we may be able to help ID them. A lot of us are bonkers for batik. I have been collecting them for years and have never had one like you describe like they had been dipped in wax. Although the method of traditional batik is wax resist. You may have initially gotten a true traditional batik panel that had that waxy feel and not what is commercially available through the major manufacturers. The most well known are Hoffman of California and Tonga by Timeless Treasures. There is also Princess Mariah batiks. And some shops, like "Sew Batik" actually commissions their own.

Edited to add that I have tried Connecting threads batiks as well and they are also very nice.
