Stamps and Stamping Supplies
You can't make a card without stamps, well you could, but stamps add more design options to your cards. There are different types of stamps on the market, and they all work very well on projects. To start off with, you want a stamp set that has a variety of sentiments in different sizes. (Happy Birthday, Thinking of You, Thank You, Get Well, Happy Anniversary, Congratulations, etc.)
The most used color stamping ink is black ink. I use two types. I don't think you need to have two types. I purchased Ranger Archival Ink first before I learned about Memento Ink. Memento is best for using colored pencils, markers and I believe it is better for use on watercolor paper. VersaMark Ink is strictly used for heat embossing. You can learn about heat embossing on YouTube. There are special powders that you apply to your ink to give it a more professional look.
Stamping Supplies
Stamping supplies: purchase a set of clear blocks to mount your stamps on and/or purchase a Stamping Tool such as a Misti Stamping Tool. It saves time when making multiple cards and lessons the amount of making mistakes.
Stamping Cleaning Pad to wash off your stamps. There is a Stamp cleaner available, but I found out that scrubbing with plain water works just as well. There is nothing you can do with strong inks such as red and black. They will stain your polymer stamps, but it doesn't ruin their ability.
Die Cutting Machines
I have two Big Shot Die Cutters. I use one of the machines, and the second one is used when my husband wants to give me a hand with bulk orders. This handy machine uses metal cutting dies to cut your paper, and it is also used for your embossing folders.
Other Optional Supplies
As you gain confidence with your card making skills, you will want to branch out. That's how every card maker ends up having a whole room full of card making supplies. There are different types of stamping methods, tools, embellishments, stickers, ephemera, embossing folders, and the list goes on. The main thing is to start off slow, have fun, and get creative. Pinterest and Card Making FB Groups will be your best friend for inspiration. Enjoy your card making journey!
