Hi, this is Cuchy, from Spain.
Don't you see pennants all over the net?.
Here you have an easy way to cut the triangles out of patterned paper.
I hope you understand my English and find the tutorial useful.
You're invited to visit my blog for other tips and tutorials.
Thanks!
1. Grab some patterned papers and a piece of squared paper, more or less the same length as the papers
2. Fold the squared paper and put some marks as a guide to cut the triangles.
I set mine 8 squares width and 9 squares height
3. Fold the patterned papers
