I tried another one of Bonny Snowdon tutorials from her Patreon subscription. I used Faber-Castell coloured pencils.
This one was drawn on Duralar Drafting Film, matte double sided 0.5. I was unable to purchase the better quality Grafix one. I’ve found if you rub too hard with an eraser on this type of drafting film, it will prevent you from adding more layers.
I’m not sure if I like drafting film.
I would add a photo credit but I currently can’t find the information at present.
For anybody wanting to learn how to draw with coloured pencils, I would highly recommend having a look at Bonny’s website. Bonny has a freebie section on her website, there are several 45 minute challenges that are for beginners. These will give you a taste of her tutoring style.
