Whenever I run a technique class I always hand out written notes that are based upon my experience or sometimes also include directions from the product packaging or company website etc. Normally we cover 3-4 different variations on one technique and then make a card using each of the techniques and do a sample swatch of it so when you have given away the lovely cards (yes they are meant to be shared not hoarded!!) you have a visual reference to them for future. These are what the sample swatches look like, from the recent masking class) that are then stuck onto the participants class note pages.
Want to join in an upcoming class - check out what is scheduled and as always feel free to suggest class themes etc that you would like to see happening.
