The first art show by Josie Russell, who was injured during a 1996 attack, has been a sell-out.
The 23-year-old said she was delighted by the response to her textile mountain pictures at the National Trust's Plas Newydd on Anglesey.
She uses mostly recycled materials, and had to restock to keep up with demand.
The artist, who survived the attack in which her mother and sister died, will show her work again at Plas Newydd before the end of the year.
"I'm really happy with the amazing response to my exhibition at Plas Newydd," said Ms Russell.
"I certainly didn't expect it to sell out so soon after opening, and I even had to introduce some new work during the exhibition to keep up with the demand," she added.
Ms Russell graduated with a BA in graphic design at Coleg Menai in Bangor, and attained a distinction in her national diploma in art and design.
She said the experience of exhibiting her work had given her "such a boost".
"I'm really looking forward to coming back to exhibit some new work in December," she added.
She her mother Lin and sister Megan were targeted by Michael Stone in Chillenden, Kent, in 1996 as they walked along a country lane.
Lin and Megan, was six - died, and Ms Russell, who was nine at the time, was seriously injured.
She later moved to Wales with her father.
Stone is serving life for the murders and will not be considered for release until 2031 after being refused a new appeal last month.
Speaking before the exhibition started at Plas Newydd she said she was fed up with being recognised for her past, but had "learned to live with it".
