I've made this set for one lovely mama here in Ukraine.
Tomato rattle is made with merserized cotton yarn and wooden beads:
There is a specific framework made with wooden beads inside. It made to keep the form and to produce a gentle and quiet rattling noise.
The cucumber measures 3,5x1,5", the tomato 2,5x2".
The onion is made with linen and cotton yarn. It is the rattle too. It measures about 2,5x2,5".
The were radish and peas also in the set.
My daughter tested the vegetables and liked them:)
