Every week I will provide a list of supplies I use for the week's mini-lesson. These will vary widely. Please do not feel as if you need to purchase every art supply or spring for the most expensive supplies. 
The list of possibilities is endless and can add up quickly. Many Art and Crafts stores have regular sales. I suggest signing up through store apps or online to receive coupons and discounts. Inexpensive supplies can also be purchased at Wal*Mart, Costco, or even the Dollar Store. 

At minimum, it is suggested that learners have a kit containing:
A journal/notebook containing sturdy paper, such as mixed media or watercolor paper of any size. (Loose paper is also okay, but it's harder to keep it all together.) 
Pencils, a good eraser, and a fine-tipped black pen
A white gel pen
Paints: watercolors and/or some acrylic paints (craft paints are fine)
Paintbrushes
Markers
an ink pad (black is best)
Glue stick and/or double sided tape
a decent pair of scissors ( close to hand size with pointy tips is best for precise cutting)
Magazines or printed out pictures from the internet, and a collection of any kind of papers: colored, white, tissue, wrapping, printed, big, small, construction, origami, whatever!
An old gift card or similar sized card (to get wrinkles out when you glue paper)
A big envelope to hold cut out pictures and other stuff for collage. 

Learners will not need to use any apps or websites beyond the standard Outschool tools.
