I do not starch my bows. I have thought about do it though...i guess I am just to lazy
I dont really think you need to buy instructions, there really arent many that you cant get free on either this site, girlythings.com or some other sites...at least for basic bows and such
I do buy ribbon sculptures and things like that though
I bought the NBNG templates and find them really helpful for at least a few bows I make that I was having difficulty with before. They really help in getting the loops perfectly even.
