I have been attending a life drawing group on Saturdays with Dinah at the New Hampshire Institute of Art. www.nhia.edu. We pay a small fee and work quietly for several hours interpreting the poses in several different media. Some folks draw, some paint,some use a computer program. I have found drawing helps me both satisfy the need to draw and put together some poses I can interpret later. I was using a bamboo pen and washes until I ran out of some excellent paper I had that absorbed the wash but left enough moisture to blur ink as it was applied. I find the bambo pen is an extension of my arm and if I train my eyes
I draw with a calligraphy pen as well. Theses drawings have been on smaller paper, 8x11. I use a delivery man's plastic clipboard with an inside compartment. In it I can carry loose paper which I find suits my style of drawing very well. I can take the paper and use it alone without having to rip apart a spiral bound notebook. The clipboard holds the paper in the wind. The compartment protects finished drawings. I use the calligraphy pen for sketching outside as well. I also carry conte crayon which I have added to some drawings. Some of these are gesture drawings are made in one minute.
Now that I ran out of the paper, which was maybe 20x 34 and was captured from a recycling bin so not easily found again, I bought some chipboard in hopes I can use it the same way. Instead I have found that oil crayons worked well for crafting an image. It is done the same way. I use a bamboo pen, study the model while my pen/arm go over the form. I have added the crayon for highlights.

Some poses have proven to be a bit stiff for further work, but may well form some library for me of images I can use as I work on pulling images together in painting.
