A yarn includes a length of straight yarn with only a leading or end portion being loopy yarn including a number of substantially equally spaced loops. The remaining or trailing portion is straight yarn joined to the leading loopy portion at a transition point. The invention can be incorporated into a ball of straight yarn provided with an accessible portion of yarn at one end of the yarn formed with loops only beyond the transition point. A method of knitting using the yarn includes the steps of inserting a knitting needle through a required or desired number of loops up to and including a loop at the transition point to form a desired number of initial stitches, and subsequently knitting with the needle using the straight yarn. The yarn and method eliminate the need to initially cast on yarn onto a needle.

Paint trapping process for textile decoration. The process described here aims to trap textile paint in order to solve the major challenges of this artisanal practice. This process consists of depositing an aqueous material (paint, watercolor, etc.) (4) delimited by zones (3), which are enclosed between two transparent fabrics (2) and (5) of the same shape, but with a slightly larger surface. This is to prevent its deterioration on each side. Once this step is completed, the user can add an additional decorative surface (1) if desired, then sew the assembly onto a textile surface (6). This process is particularly intended for the personalization of textile surfaces to enhance a garment. Figure for the abstract: fig 1.
