Here's a list of some of my favorite pastel items that would make great additions to a holiday gift list. This list is in no way sponsored, they're just items I enjoy and thought you might too!
Colour Shaper Tool- Silicone brush that's great for sharpening/cleaning up lines, removing stray pastel, and blending.
Fan Brush- Good for delicately removing/blending pastel.
Photography Tripod & SunEden Traveling Easel Adapter- Tripods don't have to be expensive, my first one (that I used for years) was $20 on Amazon. There are several tripod easel adapters on the market, I have SunEden's and like it.
Easel Butler Shelf- Hold your pastel box or other pallet right on your tripod.
Guerrilla Painter Pochade Box- Great for plein air painting, can be ordered with pastel adaptations.
Shadebuddy Umbrella- An umbrella is an essential item if you want to paint plein air. I love this one!
View Catcher- A great little composition finder.
General's Tri-Tip Eraser- Fantastic for erasing pastel on sanded paper.
These are sets I love and think make great additions to any pallet, but which pastels you decide to add depends on what you already have and what subjects you'd like to paint.
