Siyo I had a cradleboard when a baby...long long ago.... so its a bit tattered and raggedy now but I can tell you a bit about it.
Mine was a large one as my older siblings had used it before me, but it had been all redone new. Being the youngest of 10 children I feel we probley wore out a few,
Since it was a larger one, it could be used for a longer time before baby outgrew it.
It was constructed of wood base...covered with white leather and then there would be a cotton filled quilt attached to this...and another one sown togeather into a cocoon shape to put baby in...plus another one to cover it if need be. The sides of white leather was also lined in cotton quilted materials. and tied at top after baby was placed inside it all.
There was a roll bar of some sort that was also covered in the leather and beaded also. Mine didnt have lots of beads as there wasnt much to decorate with but there was all kinds of knit lace and a few big bright beads for baby to look at.
Lots of love went into this, I am sure........hugs Annie
