I love batiks and have used hundreds of yards. A couple of notes:
Do use a smaller needle size, the thightly woven higher thread count, large needles make a much larger hole than neccessary.
PRE- TREAT with Retayne , before you cut use retayne, SO MANY batiks will run/bleed. It is far better to solve this problem before assembly.
If you starch(spray) let the starch soak in for at least 30 minutes. You will get much better results.
When first starting to use batiks becareful when buying on line, the small squares that a shown may not show all of the colors in the yardage.
To start pick simple patterns that will showcase the fabric(s).
I love bargello quilts done in batiks, they always captivate me.
Batiks Are an ADDICTION.... I know of no known cure. Proceed with a budget!
