We got caps and shirts done with my husband's aunt. She has a business doing embroidery and screen printing. You can visit her site here Stitching Image. Click on services on the right hand side and then go look around !
We were happy with the quality of the shirts and hats and the customer service was second to none (and no I don't think that's only because hubby is her favorite nephew LOL)
I just got stall curtains, coats and hats as well with our logo embroidered on them. SnowyRiver Farms did it for me and they did an excellent job...in a very reasonable amount of time. :bgrin Their email is [email protected]. You can't see a lot in this picture...but at least you can see a little bit of the tack stall curtain...and the banners we're using for each of the stall fronts.
I used to get my stuff done at an embroidery business in Manassas, VA. Now I am LUCKY enough to have my Mom's company do them. She just started working for a company that does embroidery, screen printing & engraving for most of Virginia.
