I have three places that work well for me. The kitchen counter is perfect and so is my front loading washer and my dryer. The kitchen counter is self explanatory. The other two are in the basement where I have created my "quilting laboratory". I am short so these have been great and no back aches.

YOu can buy bed risers at Bed, Bath & Beyond for $10. You just place the table legs in them. It raises the table about 4".

I have a "big board" to fit on top of my ironing board. Anything would do: cutting board, plywood, etc. The ironing board can be just the right height for you to work while standing up. If you have the space, get an ironing board at a garage sale or thrift store. They are invaluable in giving you extra space to work on.

Bed risers - they work great for me.

like you we live in a RV ,MTH so make do with what you have
the counter is perfect for my mat and cutting ,I use the clubhouse's when we travel to lay quilts out to tie,sew or cut,

You can purchase the risers at Bed, Bath & Beyond or places like that. They are not too expensive. You can also raise the table to a special height for yourself by using PVC pipe - you would need to measure and purchase the correct diameter pipe - and most home improvement (Lowe's, Home Depot, OSH) might even cut it for you. Don't forget to include the addition of an end cap for each leg.

Sorry I did not read thru the entire thread so this might be duplicate information.

I have them under my table legs, and it makes it a lot easier on my back. I used the coupon at bed bath and beyond so they were pretty cheap.

It's easy to raise a table. Put four soup cans under the legs. Did this for years until the soup cans started to rust.

I use pvc pipe also.

I got a white plastic table which you can put at different heights and then I had extra holes put in the pipes and that way I can go 5 different heights. it is the 48" table but not for sure if the 60 or 72" tables has different heights. It works great. I am short and sometimes the taller tables makes my shoulders hurt.
