In the tutorial she is using the the Union command at just over the 6 minute mark. There is no group of text though it's on just the number 7 in this tutorial and then it's duplicated and one of the 7s is turned upside down. The other thing I noticed is that when I went back to try it again, it seems to work or not work sporadically. I got it to work on one of the 7s then tried it on the other and it didn't work. I then hit control Z to undo the 7 it worked on to see if I could repeat it and when I tried the union command again it didn't work. Seems really quirky, not sure if it's an issue with my computer or there is a bug in this latest version of Inkscape, or something I am doing. Thanks for your help on this!
