The pattern is written in US terms.
You may want to make the pillowcase 0.5 inches smaller than the actual pillow insert. To make sure that your pillowcase fits perfectly without any loose areas, pumps or gaps.
Your stitch count throughout the whole pattern will be 73 stitches. You may watch this tutorial and apply it throughout the pattern to help you achieve straight edges
I will be referring to the cream color with color A & to the beige with color B
Although in the first part you won’t need to change colors for the mini bo. I Recommend that you work your stitches over the beige yarn. So that you have consistency in the weight of your whole piece. Since you will do this anyways in the second and third sections.
All the rows rows between the mini bo rows are worked with color A
If you are following the written pattern you may need to take a look at the chart every now and then to make sure you are on the right track
