For scanning it really depends on what you want to do with the image after you scan it, you'll have to keep in mind the DPI(dots per inch, it will determine how much detail and the size of the image scanned) when you scan things into your scanner, generally the bigger you work the better
for stuff I post on DA its usually 100-200 DP but for things I'm getting printed I knock that up to 300
Would a pen that uses different nib tips be a spoon pen? sorry I didn't have the time to watch your video on the different pen types, but I was just curious.. as I do have that type of pen, just never used it as I am uncertain how the lining would come out and..a good surface to draw on would help too. xD
Just out of curiousity, what do you use for lining most often?
