Abstract
A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton (Fig. 1). We introduce a system to create a knitting pattern from a given 3D surface model (mainly designed for rotund animal models). A knitting pattern is an instructional diagram describing how to knit yarn to obtain a desired shape. Since the creation of knitting patterns requires special skill, this is difficult for nonprofessionals. Our system automates the process and allows anyone to obtain his or her original knitting patterns from a 3D model. The system first covers the surface of the model with parallel winding strips of constant width. The system then samples the strip at constant intervals to convert it into a knitting pattern. The result is presented in a standard visual format so that the user can easily refer it during actual knitting. We show several examples of knitted animals created using the system.

 

Abstract
Footwear in ancient Egypt was common, and although manufacturing techniques were fairly limited, the variation in forms is quite large. The present paper presents yet another category of fibre sandals: coiled sewn sandals (Fig. 1). As usual in studies of ancient Egyptian footwear, this paper focuses on the technological aspects and includes a description. Other aspects will be discussed only briefly and will be dealt with in more detail at a later stage of the project. Footwear terminology follows Goubitz et al. (2001).

 

Abstract
Small parts of toys pose a hazard to babies and young children – they can cut, choke, poison or strangle if they are not safe, or not used safely.Young babies explore their world by putting things in their mouths, but children under three years of age do not have a well-developed coughing reflex and will choke easily on small items.
