Yay, Cindy!
I'm so glad that you and your husband have made the decision about school for next year. And, I'm sure you'll be pleased with HOD as the Lord is truly at the center of it all. He will bless your decision to put Him first!
Here's a thread that explains how HOD does timelines...
viewtopic.php?f=6&t=5887 I haven't done CTC yet, but I know that all you'll need are the student notebook pages that are in the economy package. Those are used for their other history notebooking as well as the timeline that will continue on with the next 3 guides. I wouldn't get figures to cut out as those won't be necessary.
As far as materials to gather... I would read through the Introductions to the guides you're using. Here's a link to CTC...

For CTC, I think that the only specific supplies you'll need will be those for the watercolor painting to go with the poetry. Other than that, you'll need a Common Place book. This can be a bound composition book. I let Grant pick out a special one at Staples last year. We'll keep adding to it with CTC this year. You'll need either one bigger 3-ring binder or a couple smaller ones. We do one for science (notebooking and lab sheets) and one for history. If you do one big one, having some tabs to divide the subjects will be helpful. For the science pages you may want clear sheet protectors to slip the work into. That's what we've used the last couple of years with Bigger and Preparing. We've also used some cheap notebooks for English, Dictation, Creative Writing, and Math.
For LHFHG, some basic art supplies will be needed. Crayons and markers, pencils, glue (both the liquid & stick kind), washable paints, construction paper, white copy paper. For the other activities there are usually a few suggestions and they use things you have around the house. I don't look ahead and we have never had to skip anything because I didn't have something that would work - maybe postpone a day, rarely.
You'll use stuffed animals to act things out sometimes. For help memorizing the Bible verse you'll use a ball to bounce pass every unit. Masking tape is occasionally used. If you wanted to look ahead a week or 2 when you're going to the store, I'm sure it would be easy to see if you have what you'll need or not.
Two things I remember where we actually had to have the right supplies were making the "peanut butter clay" when we studied the Israelites worshipping the golden calf they made and then making our own bread when we studied Jesus miraculously feeding the 5000+.
Happy ordering and gathering!
