Do you know what a Penrose triangle is?  No, neither did I - till I saw one.  It’s what I’ve always called an impossible triangle.  (If you haven’t seen one before, try following one of the faces.  Now you know why it’s an impossible triangle!) . It was first created by the Swedish artist Oscar Reutersvärd in 1934.

The theme of this month’s Design Competition is Triangles. 

They can be literal triangles, or imaginative ones (eg a design inside a triangle.)  Whatever you think fits the theme.

The rules will be slightly different this time.  As a step in the direction of holding the competition on our website (our ultimate aim), please upload your competition designs to your account on our website.  If you haven’t already got an account, it’s simple to set up.  You just need an email address, password and name, which can be your own name, a nickname or a business name.  (You will be prompted to log in or create an account when you try to save your design.)  Then email me at admin@printmepretty.co.uk, to tell me the name of your design.  (So I can find the right one!)  I will then put them onto Facebook for voting.

So, the competition is:

Create a design suitable for printing on fabric based on triangles.

Technical matters:

Your design should be at a resolution of at least 150 dpi, but not more than 300, using RGB colour space.

When it comes to printing, the repeat options are:  Straight, Centre, Half-drop, Half-brick and Mirror.  Once you’ve uploaded your design to our website, you can play around with the repeats to see which one will look best.  For pictures of what the different repeats look like, check this blog.

To enter:

Upload your design onto our website by Wednesday, May 14th, giving it a title.  Email me at admin@printmepretty.co.uk, telling me the title of your design and the name of your account.

The closing date is midnight on Wednesday, May 14th, after which designs will be displayed (at the fat quarter size) on Facebook for voting .  Voting will close at midnight on May 21st.  The design with the most votes will win 3 metres of 100% cotton fabric (150cm wide), printed with your design.  The winning design will also be available for sale on our web site for at least 1 week after the close of voting.  

The official bit:

By entering, you agree to our competition terms and conditions.

You may only submit one entry, which must be your own work and based on the theme of Triangles.

All entries will be displayed for public voting, unless we feel that the subject matter is inappropriate.  Copyright will remain with you, but by entering the competition, you give us the right to use your design in any way we wish on our web site and social media, for advertising purposes.

The winning design will feature on our web site and will be available for sale for a week after we announce the winner.  After that time, the designer may leave the design for sale, or remove it from public view.  The designer will be paid £2 per metre commission on any sales of the design.
