There are three types of ricrac; cotton, polyester and nylon.  The cotton version is able to withstand laundering and is a good option if you are applying it to garments or items that require frequent washing – e.g., a child’s toy.  The polyester version is widely available but usually has a higher lustre and can be a little stiffer – very good for crafting but be cautious when ironing.  The third type I have mentioned is the nylon version.  This is excellent for general paper crafting and card making but melts almost as soon as you look at it so it is absolutely to be avoided when using with fabric if the item needs any kind of pressing.
