I am just in the process of orderingg more sheetz. Not all colours in the photo are available at the moment. Should have more next week.
Usually - I have a packet of each colour open at a time as I make up samples and try new creations. You can choose 3 colours in total from the colour range listed on this site. You will receive a total of 3 sheetz only. Indicate when going through checkout which colours you would like.
