Hi, my name is Mary, I see that you are struggling to draw your line on the tape. May I suggest that you use Scotch Magic tape, which you can write on, draw your lines. It's so much better than the ordinary sellotape.
First, thank you for posting this video. I found it helpful. Respectfully speaking, though, I noticed we were 5:27 minutes into the video before the actual instruction really began. Again - respectfully speaking - so, the first part of the video was kinda boring. The last part was the "meat" of the video and I enjoyed that. Thanks again for posting.
