Wow you are keen, staying up all nite sewing. Its quite easy to adjust the size of the triangles. i will try to explain for you.
Quickest way is to Click on View in the DJ software. It comes up with a box at the top of which are Blocks / Motifs /Triangles.
Its the same for blocks or triangles you can adjust the size this way. Click on Block or Triangle then click edit, this brings it on to your screen.
Go to top of the page, Click on File. Then click on Print. Now click Block or Triangle. You will see there is a size adjuster on this page for blocks its 4.5" x 4.5". You can adjust the size of your triangle here. If my memory serves me right its 5" x 8".
Hope that helps.
Yes I live in Spain, love it.
