I have used 100% cotton - Maxi 565meters on 100gr
Because you do have quetions about picture here is start of the crocheting:
You start in the middle of circle with 10 chains.
2.row: 16 SC
3.row: 3ch instead first DC, 5ch, DC repeat * * 15x - in row you have 16 5ch loops
4.row: slip stitch in middle of first loop, 5chains….
… this is start… I think you would be able now manage it…
In pattern there are only DC, SC and chains…
Hope it will help! Petra
