Star pattern Help

Hello. I am making some stars for an afghan I’m putting together. I am having a hard time after I make the first triangle. I’m not very good at picking up the stitches on the side. Does anyone have any suggestions on how to improve on the pattern to make it easier or any techniques to share, or even other small star patterns that might work better?

Do you happen to have a link to the star pattern? or the book it is from? :thumbsup:
