directions confusing

[zenkitty]

I signed up for a short class on mastering the Y seam. The supply list has 1/4 yd each for the background and the star that we will learn from. Here's my confusion: for the background fabric it says: cut one 6 1/4"x40 strip. Crosscut one 6 1/4" square. Cut the square in half twice on the diagonal to yield 4 triangles.

Ok...I am to believe that I cut the first strip and then another 61/4 x 61/4? And is crosscut mean cutting on the diagonal to make a half-square? We are making a LeMoyne Star.

Any help would be appreciated.
