I just finished a batik kit and I did not wash it because it is a wall hanging. If it was to be a full size I may have washed because I wash everything. There was plenty of fabric in my kit!

Where did you get the kit from?

in my experience the vast majority of batik fabrics are okay not to prewash as they get washed in very hot water after dyeing to remove the wax used in making the designs on the fabric.

The only color I have ever had a problem with in Batiks is Yellow. Boy does that one bleed. I just do a soak in Biz, rinse well and be sure to use a color grabber. Then press them before they are quite dry.

The last two quilt kits I used stated not to wash the fabric before cutting.

you may want to contact the shop where you purchased the kit and ask them if they intended for the pieces to be pre-washed, usually kit's are not if they are pre-cut kits. I have made literally hundreds of quilts and many of them were made with fabrics that were not washed until the quilt was quilted and bound. i never had a quilt not turn out. i have had a couple quilts have colors bleed. it is always a good idea to at least test for color-fastness. if the fabrics don't bleed, go ahead and wait to wash. it is the batting and the amount of quilting that dictates how much shrinkage a quilt has.

I am also getting a blue batik kit, and I will not be washing it before I sew. I purchased the kit from ebay from a seller that has a good report. It also is exact cut.

I like ckcowl's suggestion to test for color-fastness. I wouldn't want to pre-wash unless the colors bleed.

i made a a card trick out itassorted material did not wash till done put a color catcher in wash came out lovely the person who i gave it to has since washed it no problems

To wash or not to wash. As many different answers as there are quilters. Personally, I wash all my fabric then spray starch the daylights out of it when I use it. I LOVE batiks!!! Really love them. I bought some Bali Pops in reds and blues and was very concerned with them running. You certainly can't put them in a washing machine!!! I took the strips and soaked them in a basin in very hot, hot water and then gently dried them in a towel then ironed them. Worked fine and no bleeding. I have since then started using this same method with anything less than a yard. I have been tremendously amazed at how much they bleed. I have been known to soak a piece3 or 4 times to get out some of the dyes. I'm nervous about a project I'm almost done with and will wash it with Retayne when I'm done.
