I decided to test myself doing this challenge, but making a short YouTube video, giving me a chance to listen to my sentences to see if they actually made any kind of sense. I also thought it would be great to have this as a record of my progress that I can look back on later.
I can see that I made some mistakes, and there are some guesses. But given I am completely new to Welsh, I am really pleased! The video is here in case anyone is interested.
