If you follow the link here, you will find DMC, l’arte del filo. Translated to English it means DMC, the wire art. They have many free charts for you to download.
I particularly liked this one (Pianta grassa fiorita)
and this one (Sedum Aurora)
They will say GRATIS in the price field if they are free. The download button reads: SCARICA LO SCHEMA. You will be required to give them your email address.
Have a nice look around. You are very likely to find others you like.
