You're going to put those stitches 'on hold' for later. Use a tapestry needle or large-eyed needle and pull a strand of contrasting color yarn through the stitches and then remove the knitting needle. Now the stitches will be held on the spare yarn.
When you get to the point where you need these stitches, you reinsert your knitting needle through without losing stitches. This pattern suggests leaving the spare yarn in the stitches as you finish the fingers in case you need to rip back--your spare yarn will serve as a lifeline that you can rip out to and not lose stitches.
"Trust the pattern!"
Time flies like an arrow, but fruit flies like a banana.
Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
