I'm glad I could help. Just hang in there you'll get it.
I'm just surprised that the pattern didn't call for you to do a base chain---chain 3, slip stitch (sl) in 1st chain (this makes a circle) then you need to get the next row height--HDC is 2 chain, 'turn' then do the half double crochet into the circle you made with the 'chain 3, sl in 1st chain.' I am gonna' do the 3 rows you posted. Something seems funny to me, but until I work it up I can't tell you.
My second love to quilting is crochet. I know HOW to knit, but there are to many stitches to worry about and I really know how to miss stitch several rows before I know I missed them!! With crochet you only need to worry about one loop!
What I really like working with it the # 80 crochet cotton that works up into filet crochet in doilies. I have made 3 'The Last Supper' wall hangings over the years and an oval table cloth plus countless smaller projects. It's easy to do in front of the TV and I like to keep my hands busy. Right now I am working on a shawl for church.
I shall be back after I work this pattern a little.
