I purchased a piece of white taffeta w/ black frock design on it. Is there going to be a problem with the cleaning care of it because of the frock?
By frock, you probably mean flock. Please ask the store where you purchased the fabric as they should have given you care instructions. Flocked fabric can either be dry cleaned or washed depending on what the fabric manufacturer states. The glue that is used to flock the fabric is the key to care instructions.
If you are unable to contact the fabric mill regarding care instructions, test a small swatch yourself by washing it and drying it to see if the flocking stays.
Hope this helps!
