I made one and LOVE it. The triangle in a square units, which form the star, are not the easiest thing to get right, or at least weren't for me - and I've been sewing for over 40 years, quilting for 15 or so.
That said, Bonnie does provide excellent and throrough instructions. Her website (quiltville.com) also has an extensive list of free patterns, as well as other sewing, cutting and stash using tips. Do you have scraps that could be used for whatever quilt you do with your daughter? The variety in Bonnie's quilts is what makes them sparkle. My Cathedral Star is much like Bonnie's as far as those units that are consistent, the red, bllue and black. The rest came mostly from my stash, although it was hard to find anything bright or jewel toned. It really made me realize how much I lean toward darker, muted colors.
