Merry Christmas! I have three versions of this Christmas Tree.
Here is the first:
Here is the second version:
Hopefully you have caught on to the pattern: Repeat rows 5-6 decreasing one dc for the shell until you do 1 dc for the shell. Then:
sc in each dc and a final row of a sc in each sc. Finish off.
My first two trees were smaller version. If you want to make smaller version, chain 36 instead. Skip 2 chains between single crochets and shells. my first tree I started out with 5 dc shell on the first two rows and my second tree I started out with a 6 dc shell on the first two rows.
