For the kids at St. Mark School, which her 9-year-old son, David, attends, she made a custom shirt for purple Fridays.
It reads, 'Respect This House,' and has a picture of the St. Mark Lion mascot sitting on the school.
"We can put on any phrases (on a T-shirt) — nice phrases though," Welsh said. "It's like a circus. If it makes people smile, that's my goal."
At Super Bowl XLVII in New Orleans, she had the idea to sell jumbo Ravens purple beads and, with the help of Tracey Wheeler, who added logos to the bling, then displays them in her store.
"I love to help out local creative people, so some of the things in here are made by artists," said Welsh, noting she offers a special section of Ravens drinking glasses, designed by Linda Lewis, and photographs, taken by Dennis Knowles and Beth Tenser, for sale.
It features Ray Lewis' last tackle in the center, with photos of several of the icon's memorable moments. Included are shots of his last dance, final embrace and final play in a collage that rings the border of the print.
Noting how popular the retired linebacker was at the Super Bowl, when a vendor sold 30,000 purple T-shirts with number 52 and just the word "Thanks" above it, Welsh knows that many Raven fans' fondness for Lewis runs deep.
Tom McGrath, a frequent visitor to the shop, sported one of the shirts at the shop recently.
"She can get anything," he said. "She comes up with those logos, and she gets them sent to her. They are perfect and they are all custom made."
She also designs her own logos on a computer and orders them from China.
"They make them and ship them, and I heat-press them right here," she said.
It takes about 10 seconds to heat press the logo on a T-shirt with the press set at 360 degrees, she said.
"I try to have something for all sizes, too, from little girls to large women, something for everybody," said Welsh, who said she fell in love with bling while being a majorette for 16 years. "I love bling and fun stuff for parties."
