I just had a Very Good experience dealing with Yolanda at- www.ynrmotorsports.com !!
They do custom Embroidery on caps,jackets,banners and other stuff for racers at a VERY reasonable price. Like high quality caps with whatever you want embroidered on them for $4.50 each-min. order 12-in your choice of colors in cap and thread. That is they don't all have to be the same colors. They can do any size order,big or small.
Their communication was Outstanding and they took my Idea and made some proofs that they Emailed to me for my approval and NO set-up charge like the local shops wanted.
