I am knitting the Textured Treasure Afghan by Lionbrand. The pattern is as follows:
With 2 strands of yarn held together, cast on 40 stitches.
Knit 4 rows.
Row 1: Knit 4, place marker, purl 8, place marker, * [color=red](knit 1, purl 1, knit 1) all into next st, purl 3 together;[/color] repeat from * to last 12 sts, place marker, purl 8, place marker, knit 4.
Rows 2 and 4: Knit 12, purl 16, knit 12.
Row 3: Knit 4, purl 8, [color=red]* purl 3 together, (knit 1, purl 1, knit 1) all into next st;[/color] repeat from * to last 12 sts, purl 8, knit 4.
Repeat Rows 1-4 for total of 68 rows, end with a Row 4. Knit 3 rows. Bind off. Weave in ends.
I have cast on and knitted the first four rows. After that I get lost. I understand the plain knit and purl but I'm not sure what the instructions I highlighted in red mean. What does the "all into next stitch" mean in row 1? And in Row 3, what does purl 3 together mean and then the same "all into next stitch" notation? This is supposed to be an easy pattern and I am a beginning knitter. If explained I am sure I can do the stitches, I just don't understand. Thanks in advance.
