We had nearly 40 people at our last crop, and the kit that day was very popular. The technique was using alcohol inks, and we enjoyed getting messy! This is the layout that I did:
I used the inks on photo paper to create the circle, then on a ghost flower and on a metal circle to show how they can be used on different surfaces. I still have a few kits left over so I have put them on the website here. They're £2.50 and include everything you need to create the layout except the alcohol inks themselves and the lettering - I used some Li'l Davis stamps and a Heidi Swapp chipboard M on the metal tag. Full instructions are included too!
