Thank you all for the replies!
@loxdust, you can't really get the same effect with pencils. I like to put a flat colour of markers down then add a little Prismacolor over the top.
And no, they aren't cheap, I paid £130 for my set, but they are worth every penny, I assure you. I have tried Letraset, but I didn't find them to be as blendable, I thought they were like felt-tip pens for adults XD
I've been a busy bee, and so made a few more VG related and non VG ones over the past few days! Find them attached
I'm starting to stick things and add real items to my paperchildren. Makes them look even more "interative", I feel!
