Temperature cross stitch

[netto]

I'd like to do something like this, but a temperature one,for a wedding later this year.
Has anyone seen any kits?
I don't trust myself to work out the colours.
Thank you

I think these are beautiful, I’ve been looking at knitting along the same lines. Etsy has some kits but seems to be mainly patterns: https://www.etsy.com/uk/listing/973261473/wonderful-wildflowers-modern-cross?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=temperature+cross+stitch+kit&ref=sc_gallery-1-11&sts=1&local_signal_search=1&plkey=c5601f3f6cdb07ec23cec5060a50a9dddb8bee04%3A973261473
