Cut two 30cm long x 4cm wide strips of different colours. The length of the strips matches the circumference of the glass + 1.5 cm. Draw flowers or other motifs of your choice (2 different sizes) which you will apply on the width of the strips. Attach the flowers on the coloured strips with paper fasteners (make a hole first with a Stanley knife). Place the strip over the glass so that it fits it properly. Check the place where the two sides join so that the sleeve wraps the glass properly and attach a fastener. This way, the sleeve can be removed before the glass is washed and put back into place (from the bottom up).
