Cob: garden sculpture

[susie osler]

hi all,

someone recently posted that they have made garden planters with lime,
clay, sand and shredded newspaper that have stood up to water contact.  i
am wondering if this lime mixture is safe for kids to handle (and sculpt
larger garden ornaments) from.  also, what percentage of lime to clay to
sand to paper,etc. would you recommend???

thanks, and hope everyone has a great cobbing year!
