Many who are enjoyers of tea also tend to be enjoyers of collecting and innovating/repurposing. These Ikebana screen are used for flower arrangement but also make a really cool tea table. Yes a bit unstable, but this can easily be rectified by using a small plate or piece of wood to balance your wares. 
A towel can be discretely placed underneath or you can use a large bowl to balance the bamboo fence on top. Personally we use a old flower arrangement flower pot because it is huge :D
