When browsing for art and craft supplies you may come across some papers with names you have not met before. We provide a short glossary elsewhere [125408], which provides basic information, with links for more details (when our own notes are available).
I have provided a price-guide, which is not reliable for those going shopping. The intent is to indicate costs relative to each other. An A4 sheet of office paper will cost around 1p ~ a similar sheet of Khadi paper may cost 50p ~ and Chiyogami around 200p. This is only a vague guide since the 'cost of an A4 sheet' is very much theoretical. Also I may not yet have found the best supplier.
Most of these papers are made in sizes other than A4, and can usually only be purchased in those larger sizes. An exception to this is in some craft shops ~ such as our sister site BusyBusyDotShop ~ where cut-down sizes are available for some papers.
