Here’s the final outcome: my Husband cut two pieces of particle board and put them under each section of legs:
This board was NOT supposed to wobble, but it does! I initially put this in another room with a flat floor, and it wobbled. 😦 So, as my Husband needed to store some of his pantings in that same room, so I moved it onto my sewing room rug, and just as expected, it wobbled there, too. SO: these 3/4″ particle boards provided the surface tension necessary and the rug actually helped to support that theory! It is now approximately 95% wobble free while ironing.
Happy sewing and crafting (and ironing!). 🙂
