If you haven't a good idea about what to make for this week's theme, you might like to have a look at the website below.
I found this for a 1-hour flapper's dress - I've had a play with it and while it has taken me more than one hour, I can see that it would be done in that time frame if you are suitably organised.
There is a price for the download, but I'm happy with what I received in the download.
I'll post the pic of my dress with me wearing it, if I'm feeling brave lol, else Gertie will be resplendent in it. Cheers, Jen
