The wooden mallet that a judge uses in court is called a gavel.
I made a gavel & sound block by my husband request. Yarns used light and dark brown.
Hook 3.5mm/E/4. The gavel & sound block sizes are as the same as real ones.
I made them probably in 3 hours. I can give approximately pattern for them if anyone interested :)
