More trees (with various pen tools)

Another demo video. Although not a folded pen, am still sharing, since it's Cmas time!

Trees made with my Pilot Parallel pen. Hold upright and move back and forth down the paper, again, making longer strokes. You could probably get the same effect using any type of chisel nib, but the Parallel pen has continuous ink flow (b/c of the cartridge). 

Others:

With colorful dots, Gold & Silver, then just Red.

These are 3 I did this summer for my "12 Days of Cmas in July" on IG:

Again, used Pilot Parallel Pen. Big one on Left was done with broad edge of pen, then added accidental accents, as the ink in the cartridge bleeds b/c it's not waterproof.  😕  Top Right one was done with the end straight up & down and at an angle, back and forth strokes, and Bottom Right was various swoosh marks.

Here is yet another using this pen. All I did for this one was to make a straight line, then with a fine tip brush, use the ink (since it's non-waterproof) to make the tree branches.

With a chisel nib and india ink:

Did this last year with my Hiro Poster nib.

Decorated. Again, wish I had scanned in first!
