K5tog (Knit 5 together)
The pattern author presents an alternative decrease in case knitting 5 stitches together is difficult; slip 2 sts knitwise together, k3tog, pass slipped sts over. We tried the alternate and think it looks and feels great. You can see the alternate version of k5tog in this decrease row video.

Stacked Increases and Decreases
This block uses a special technique of stacked increases and decreases to create interesting fingerlike bands of color. The number of stitches after the increase row goes from 49 sts up to 169 sts and is later decreased back down to 49 sts in the decrease row. Because you will be carrying so many stitches on the needles you may find it helpful to use a circular knitting needle to accommodate all of the stitches. While knitting this technique we noticed that the stitches would get tight from time to time and that using metal needles allowed the stitches to slip more freely on the slip-back (SB).
The following videos are an excellent introduction to become familiar with the general concept of stacked increases and decreases. After that are links demonstrating the techniques in the specific sequence specified in Increase row 1 and Decrease row 3 of the Block #22 pattern.
