This is a center out pattern in US terms
 
101 rounds and 201 stitches per side of your last round.
 
All squared;
In DK yarn 107cm/42inches.
In 4ply yarn 81cm/34inches.
In Aran/worsted yarn 49inches/124.5cm.
 
I love everything to do with nature and wanted to do a center out
design. There is a video below of the first 8 rounds below to get you started. Natures Spirit is 101 rounds, so smaller than previous patterns, the last round has 201 stitches per side and is an overlay mosaic crochet pattern using US crochet terms. If you want the blanket larger you can use a thicker yarn such as
Aran/worsted.
 
The pattern includes a fully written pattern, charts, a full chart and a video of the first 8 rounds to get you started here;
