My brother in law is a Tongan living in New Zealand, and recently had a family member send him a large piece of cloth to try an experiment or two. I jumped on the band wagon and dyed a tiny piece today with liquid dye paints. The colors took very well. Nothing has come to mind yet as to what to do with the tapa I have. Fabric artists/textile artists would likely jump at it.
I may quilt a piece. Whatever I decide, it is too precious to just sit and gather dust.
