Start your interchangeable set slowly with this kit that includes just the essentials. There are six pairs of needle tips in Kollage's signature square shape - sizes US 4 (3.5mm), US 5 (3.75mm), US 6 (4mm), US 7 (4.5mm), US 8 (5mm), and US 9 (5.5mm). Many find that the square shape is easier on the hands, making them ideal for those suffering from arthritis or other painful conditions. Some people also notice that using square needles helps make their stitches more regular and even. You'll also get three firm cables to form 24", 32", and 40" needles, as well as the necessary tweezer tool. The kit comes packaged in a compact, canvas case. Ribbon colors will vary - please let us choose for you.
