Just received a call from my dd in FL who wants to remove a logo that is on the back of her son's Karate uniform jacket. She thinks it is probably some kind of "painted on" logo as it is not an iron-on nor a patch. So, the question is how to remove this? The jacket is a cotton/synthetic combination and is "canvas-like" if you know what I mean or have seen these uniforms. I has been through several wash cycles. I thought maybe a bleach pen might work or perhaps painting over it in white to match the fabric. The other idea was to sew a patch of similar fabric over the logo but I don't think she wants to do this. Does anyone know if either of these would work or maybe have a better idea ... assuming it can be done? Thanks for any and all help! KLO
