The Welsh resurgence stalled with a 36-15 defeat in Ireland but Thomas, who stood in for injured skipper Colin Charvis, believes it can be kickstarted when France visit Cardiff on Sunday in the RBS 6 Nations.
"It will be a big bonus to be back on home soil, on familiar territory in front of our own fans for the France game," said Thomas.
"The atmosphere in the Millennium Stadium was awesome against the Scots and the Ireland defeat adds an edge to the game for us.
"Losing that game was so disappointing because we really thought we had come such a long way in 12 months.
"To lose in the way we did just adds to that disappointment but now we must that behind us and look forward to the next game.
"France are one of the best four sides in the world and we just have to play and express ourselves in the way we have proved we can in the past.
"We must put the defeat against Ireland into perspective, learn from our mistakes and remind ourselves that we are better than that.
"The squad give 100% and have a positive attitude. You can't doubt the commitment of anyone in this squad at the moment but every game throws up something different and that's the lesson for us to learn."
