One of the grumpiest and intelligent muppets from Sesame Street - Bert makes a surprisingly very cute baby rattle :) The skill level required for this pattern is Advance Beginner. The pattern comes with detailed written instructions and charts (if you prefer to use them). The pattern is my own inspired by the confusingly adorable Bert from Sesame Street. Note - I'm not affiliated with Sesame Street. (sigh) *You may NOT use this pattern, or the dolls produced following the pattern for commercial/retail purposes. BASIC SKILLS NECESSARY Increase and Decrease Change Colors GAUGE No need for gauge. You can change the size to be bigger or smaller by using threads in different thickness and different hook sizes. SIZING / FINISHED MEASUREMENTS The rattle measures about 6.5 inches high and about 2.5 inches at the widest point.
