I often see questions about which inkpads are suitable for various techniques and thought I'd link to this excellent webpage which covers everything really clearly. Ink pads explained For anyone who doesn't trust links like that, this is the URL  http://www.cardmakingparadise.com/ink_pads_explained.html
Sorry for title being all in uppercase but I wanted it to stand out as it's such a helpful site - and I refer to it regularly when my poor old brain forgets something. Embarassed
