This is a simple lace pattern, based on the scripture

Mal 3:10 Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the LORD of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it.

Can be knitted with any color cotton you like both variegated and solid colors are fine, even self striping would look awesome.

Size varies depending on your knitting style and needle size
mine came out to be appx 7X8
