I think I’m being a bit stupid here, because I have no idea what I’m doing wrong (sorry 
)
To me, this should be simple. Draw around an object, scan the image, import the *.jpg into CC. What’s difficult about that?
I downloaded Inkscape and had a play around, and it is very easy to play with, but simple things I can do. but not this.
However I do it, the image is giant-sized. Essentially, I’ve followed the first step in the tutorial you did for photo tracing, using a scanned drawing rather than a photo, but the second step where you say to resize the image in an editor? Why would that be necessary? Surely it’s been scanned at the actual size?
Sorry if I sound grumpy; I’m a bit tired and finding this a bit irritating.
