Rippling 4 week mark

I have been doing the rippling crochet for four weeks now, slowly progressing, I have now decided to continue until it is a square to make a knee rug.

We have had 68mm of rain overnight and some more showers this morning, the water runs down onto the cement slab at the rear of the house so we are considering building a low retaining wall just out from the rear covered area and levelling the grassed area so that the water will not run onto the slab.

The four new grevilleas photo as promised we are going to cover this area with sugar cane mulch, we intend to also get rid of some other areas of grass.
the grevillea varieties are "Flamingo", "Just Peachy", "Moonlight" and "Firesprite"
