This is the Stasha 'Tweed' special edition. Covered with a natural Flax material and epoxy. It is 50% heavier than a standard Stasha and it takes about three times longer to build. If you would like to build a Stasha 'Tweed' you will need a set of Stasha plans and this article which will tell you all you need to know. Please note the Stasha 'Tweed' is harder to build than a standard Stasha and it requires a higher level of skill. The end result is splendid though.
