From the pattern description:

These delicate bags, decorated with simple stitch-textured hearts, are trimmed with a lacy edging and tied up with pretty ribbons threaded through eyelets.

Small projects in basic fabrics but lacy edgings and working stitch patterns from a chart may be a challenge for a beginner.
