Draw two or three tulips in different sizes on a cardboard box. Cut them. Shake the bottle of blockprint carefully to be sure oil will mix with the rest. Drip some paint on the glass and roll it out with the lino roller. Roll the paint on the tulips and press them on a white or coloured sheet, using a book. Remove the tulips of the sheet and roll them again. Add white to the colour on the glass for a lighter colour. Place the tulips tulips partly overlapping the first, and press again with a book.
