Funky Friends Factory Gertrude Guinea Pig Pattern. Gertrude wants you to know she is not from Guinea nor is she a pig! Her ancestors came from the Andes mountains but these days they prefer the comforts of human homes and they are very affectionate and responsive to handling and feeding, but mostly feeding! This simple pattern looks fantastic in any fabric and is a great stash-busting pattern too! Pattern includes color photo, full list of material requirements, layout diagram, and easy to follow instructions. Finished toy is about 12 inch long.
