Hmmm, I've been thinking about what my favorite products are from CTMH. It's a cross between the clear stamps and our "how-to" books.
I remember using CTMH wooden stamps when I first started making cards and scrapbooking. When CTMH changed over to clear stamps, I was upset. I didn't like change, I didn't get it, I was used to my wooden stamps, and I just wasn't going to do it! THEN, I started using the clear stamps with the acrylix blocks. Wow! What a difference. I could see EXACTLY where I needed to stamp - no more guessing and re-stamping. It was much easier to store the stamps - took less room. Now, when someone wants to lend me a stamp set that's not clear, I really hesitate because I can't see through the wooden block to place the image.
My other favorite CTMH product has to be our "how-to" books for card making. We have 2 just for card making: the Originals Card Confidence Program and the Wishes Card Confidence Program.
I own each and everyone of our "how to" books but lately I have referring to Originals and Wishes because I've been into making cards. Each book as a TON of patterns and pictures of cards. They give you step-by-step instructions for the cards. They can be used by beginners and advanced card makers alike. When I need to jumpstart my creativity, I pull out one of these books to get me started. Inevitably, I end up changing the card around to make it more my own. I would definitely recommend these books to anyone who likes to create cards.
