Little Rattie stands just 9 inches/23cms (approximately) tall. He is knitted flat and assembled and has a choice of a tutu or little vest to keep him warm. He has whiskers and embroidered eyes, full directions are included to create these. You could of course use toy safety eyes, I would advise 8 or 10mm.
If these are being given to a baby I would suggest knitting these with nice soft cotton Aran/worsted weight yarn but I have had great results using acrylic and wool yarns too.
For an older child/adult of course you can use a variety of textured, furry/fuzzy yarns. There are so many readily available today that we are quite spoilt for choice. Please see yarn suggestions below to see what I have already tried.
If you wish to use double knit please lower your needle size to 3mm/3US. Your character will be a little smaller.
