Valentine’s Day suggestions that are guaranteed to be finished in time:

The heart is quick to crochet and can be used in many ways: as a cutlery pouch and coaster for a romantic dinner for two, as a pincushion, or as a gift or flower tag...
All you need is some leftover yarn in 2 colors, a crochet hook, 1–2 hours of time
and the crochet pattern!

This heart with the sweet little bears has already brought joy to many people and is a loving little gift for Valentine’s Day. Here, too, you can rummage through your leftover yarn and don’t need to buy any new yarn.

If your sweetheart is a bookworm, he’s sure to be happy about one of the two bookmarks (or maybe even both?). Both are crocheted from leftover yarn and feature a heart motif. On the bookmark on the left, the heart is worked as a lace pattern; on the one on the right, it consists of individual hearts decorated with small rocaille beads.
Here you can get the crochet pattern for the two heart bookmarks!
