Here are scans of Swedish pastepapers. Pastepapers are made by adding color to a carrier, like corn starch, wheat or rice paste, methylcellulose or other materials. Good pastepaper makers have very specific recipies. A reference book for this is: Marbled and Paste Papers, Rosamond Loring's Recipe Book.
Basically the color is applied to the paper and then manipulated by dragging things over the paper. Think finger painting, but in a much more controlled way. But no less fun!
These are particularly beautiful examples and I hope you enjoy look these over. They were all scanned next to a ruler so you will have an accurate representation of the size of the pattern.
