I'm working on making our laundry not-so-ugly by:
Step 1: Doing a BIG clean-out / tidy-up / wipe-down
Step 2: Putting together pots of succulents, and placing by the window.
Step 3: Painting the rusty, peeling under-sink cupboard, and the little wall-shelf to match.
Step 4: Curtains!
Step 5: Hide clutter along wall.
Not sure how I'll approach Step 5, but 1 - 4 have been successful!
(I wish I'd taken 'before' pictures - believe me, although still pretty ugly, it's much nicer than it was!)
