This pattern calls for a DK weight yarn - one or two skeins, depending on the yarn. This fingerless mitt lace design creates a single heart on both sides of the glove, so each mitt made is interchangeable.

Two pairs of mittens are shown here; each with a different yarn.

The level of difficulty advanced beginner because the second half of the heart pattern is more difficult than the first, requiring a little more knowledge and concentration.
