Using some basic textured stitches:
Make a row of single crochet. Turn. Make another row of single crochet but this time pass the hook through the back part (or back loop) only of the stitches of the preceding row. Use different colors for each row to emphasize the effect of the stitches.
Start with a row of simple treble stitches. The row with the raised treble stitches consists of three simple treble stitches, then one double treble connected with a loop trough the stitch of the previous row. Continue with three simple treble stitches then one double treble, and so on. Use different colors for each row so that the raised treble stitch is more visible.
The pattern is made up of three rounds of stacked shells that area laced together with chain stitches in the third round of the sequence. Each shell is made by working (2 dc, ch 2, 2 dc) in the same stitch or space.
Row 1. (2 dc, ch 2, 2 dc) in next stitch, ch 2, skip next 2 stitches; repeat from * to end. Turn.
Rows 2 and 3. (2 dc, ch 2, 2 dc) in ch-2 space of first shell, *ch 2, (2 dc, ch 2, 2 dc) in ch-2 space of next shell; repeat from * to end. Turn.
Row 4. (2 dc, ch 2, 2 dc) in ch-2 space of first shell, *ch 3, sc in ch-2 space between 2 shells two rounds below, ch 3, (2 dc, ch 2, 2 dc) in ch-2 space of next shell; repeat from * to end. Turn.
Row 5-7. Repeat Rows 2-4.
Make a wrap-around skirt of at least 4 colors.
