Timeless Tresures makes a very high quality Batik and non- batik. DO PREWASH !! Many of the batiks I have purchased in the last few years ...run like crazy. It does not matter who the manufacture was ... Hoffman, Moda, Robert Kaufman .... Prewash and or treat with Retain. The deeply colored Batiks are the worst at running. I was going to make a quilt with all deep jewel tones... and good thing I tested first or I would have just cried when the quilt was done. Every single piece ran ( and there were pieces from just about every major compnay).
Once a quilt is finished use Synthropol in the wash .. .just incase the running was not quite done.
Do not beleive that once washed and machine dried that the heat from the dryer and iron will finish setting any dye.... I do not know why the manufactures can not improve this ?!
