How to Crochet Triangles Top-Down - Raffamusa Designs — *1 – Half granny square triangle; 2 – Half solid square triangle; 3 – Half square triangle without gaps; 4 – Double crochet triangles for shawls and scarves.*

The more classic half granny square triangle is the one that is labeled 1 in the picture above.

However, when I talk about half-square solid triangles I mean triangles number 2 and 3 in the picture above. These are exactly half a solid granny square folded along the diagonal.

The two types of half-square solid triangles are:

Classic double crochet triangle (number 2 in the picture above)
Completely solid triangle without gaps (number 3 in the picture above)

Classic Half Solid Granny Square

The classic double crochet triangle is half a classic solid granny square if you cut the square along the diagonal (see pic below).

This half-square triangle is perfect for making blankets, garment elements, decorative projects, etc.

Of course, remember that if you’d like to crochet a triangle scarf or shawl, it is best to use a solid double-crochet triangle that does not make a right angle at the tip. Instead, I suggest you try this slight variation HERE that has the shape of an isosceles obtuse triangle.

Half Solid Granny Square – Without Any Gaps!

Going back to the half-square triangles that we’ll see in this post, the second one is a completely solid triangle without gaps. This is half a completely solid granny square, which does not have any gaps or holes, not even at the corners or the tip (see picture below).
