I created the chart for my Union Jack back in 2016 as a pen wrap, selling it as a full kit or just the colour chart. Although we no longer sell the pens, the colour chart has remained available to download or as a printed copy.
To celebrate this special Platinum Jubilee Year, I have made the flag and flag pole available as a full kit (£14.50), bead pack (£7.95), full instructions to download or as a printed pattern (£8.95), as well as keeping the colour chart available on its own (£1.50).
