TEN years of hard work have finally paid off for textile lover Margaret Armstrong.

She was announced the overall winner of the best themed tree in this year's Jumpers and Jazz Festival Tree Jumper Exhibition.

The winners were announced at the festival launch party held at the Warwick Art Gallery on Friday night.

Every year for the 10 years of the festival's history, Margaret has produced a beautiful tree but this year's was something extra special.

"It took me about three weeks and some very late nights," Mrs Armstrong said.

"I really enjoy doing it.

"I'd had ABBA on my mind for the theme for a while and it just all sort of came together."

The tree jumper exhibition was judged by Lyn Baxter and Sue Ford who are the Queensland president and vice-president of the Australian Textile Arts and Surface Design Association.

Festival art director Karina Devine said this year's Mamma Mia theme has injected some poignant emotion into the tree jumper artworks, with many artists carefully considering the mother-child relationship angle.

"The tree jumper exhibition is always colourful and often quite humorous but this year, it has been delightful to see some very thought-provoking artworks," Ms Devine said.

"All of our tree jumper artists are to be congratulated on their creations and how they have embraced the theme and our much-loved festival."

Friday night's launch saw about 200 guests, including Member for Southern Downs Lawrence Springborg, Southern Downs Mayor Peter Blundell, tree jumper artists, local business operators, sponsors and festival friends gather at the Warwick Art Gallery to hear the winners announced.

The Warwick Art Gallery courtyard was yarn-bombed to perfection and hip Australian jazz band, SCAT performed on stage throughout the evening while guests wandered in and out of the Portraits of a Tea Cosy exhibition.

Guests took the opportunity to dress for the occasion in quirky woollens and winter fashion and weren't afraid to dabble with colour.
