Well, some of it is for the upcoming year. I purchased RTR for my oldest who is about to finish CTC. He loves HOD so much, he doesn't want to miss out on the last guide, so he's doing CTC at five days per week to make up for lost time in the past! 
We'll only do this until he's finished with MTMM, then we'll be right on track to just go at a four day a week pace for the rest of the guides! I just have to say that I absolutely LOVE the way RTR is put together. All of the materials are so carefully chosen, and intertwined together with God's Word to create such a beautiful way to learn about this time period. I am so thankful for the talent that God has given to Carrie Austin, to bless all of us with this amazing curriculum!
Reading through the guide, I did see that oil pastels will be needed for some of the history projects. I was wondering what others have used, who've done this guide before us? I was thinking about just getting the ones that Miller Pads and Paper sell, but would I need a larger set of colors or a 12 or 24 color set? I just want to have the right thing, so the projects move along smoothly.
Any other helpful supplies, or suggestions on what to do to get ready for RTR, would be much appreciated! Looking forward to another amazing HOD guide.. . . .
Blessings!
