There are 4 rows so the triangles will be 3.75” high.
I should be able to draw the triangles.
I agree that there are four rows.
It looks to me like there are 6 trees in the top row, 5 in the second row, 6 in the third row, and 5 trees in the bottom row. (If I were making it, I would have 6 trees in the bottom row, and a 5 tree row on the top.)
I think the maker used cording around the edge of the pillow.
I think the ratio that would work would be a width to height ratio of 2:3.
Example, If the base of the triangle is two inches, the height would be 3 inches. (2 x 6 = 12 for the width and 4 x 3 = 12 for the height)
Base - 2.5, Height - 3.75 (2.5 x 6 = 15 for the width, and 4 x 3.75 = 15 for the height)
Base - 3, Height - 4.5 ( 18 for the width, 18 for the height)
You can change the ratio to whatever looks attractive to you.
The triangle-in-a-square tool/ruler (Tri-Recs), the base of the "fat" triangle is equal to the height.
I have attached another drawing for comparison of the triangles, using 3.75 inches for the height.
