We employ many of the strategies already mentioned.
Another one is I removed the chair in our bedroom. I did sit in the chair to apply makeup and do my hair or DD's hair, etc. However, the chair ALWAYS had stuff on it. Bugged me. I have an exercise ball that was always roaming around the house. I moved it to the vanity as my "chair". Ahhhh!!!!
Also, we have a master bathroom right inside our master bedroom doorway. We put an 8-hook (two rows of four hooks) over-the-door rack on the OUTSIDE of the bathroom door for our "re-use" clothing. DH has right side (2 upper and 2 lower hooks) and I have the left side (same). It is always accessible (even when someone is in the bathroom with the door closed), but not obvious when the bathroom door is open (which is most of the time) due to the arrangement of doors and natural lighting. The clothing airs out very nicely and we have learned over time to keep the items to a minimum. Once in awhile it gets too full and I just toss everything into the laundry sorter. When I need a few items to fill a load for the washer, I'll raid our hooks or DD's hooks. She has a wood rack on her closet wall (tiny walk-in style; our closet is very different and this didn't work for us).
Like a PP, I will wait to dry clothes until I can pull the items out and get them put away right away. I do it more due to wrinkles, though. I don't iron clothes! (I do iron crafts.) I also line dry. Linens go outside. Clothing is usually on a wood folding rack in our bedroom due to space and airflow and warmth/dryness. I place the rack right behind my "ball chair", so it cannot live there long.
I think the biggest thing for me/us is making the mental/emotional shift. Our bedroom is an important space and let's treat it as such. I use our bedroom for quite a few activities and I love it in here now! I have my makeup and hair stuff in a vanity (old-fashioned small desk with new glass top and new hardware). I also store my essential oils and carrier oils and tinctures and other such items here. I have a small cabinet with three shelves behind a door plus a drawer and slide-out shelf. I keep a stainless steel tray under the cabinet for mixing and such. I also meditate in this room. It is a wonderful space!
We have several lighting sources:
1) soft overhead lighting via switch (low wattage bulb in frosted globe, which is a light kit on the ceiling fan);
2) bright/strong light behind the headboard for reading (tall uplight, which I leave on but unplugged for convenience and safety);
3) small crystal "romance" lamp across from the bed (simulates candlelight without the risks; also left on and unplugged when not in use);
4) lighted vanity mirror for makeup and eyebrow tweezing and other close work (it's a pretty stainless steel version...one of two items kept plugged in in our bedroom -- other is clock radio with battery back-up); and
5) our bedroom has a six-foot by five-foot window that faces due West for plenty of luscious natural light by day. In the winter, we keep the blinds closed at night and open during the day via twisting the wand (angle of blinds). In the summer, we close the blinds fairly tight regarding the angle during the day, but keep them slid open a couples inches from the end for some natural light...and open them further at night via sliding them as far open as the window is open to increase the cool night airflow without listening to the flapping blinds.
We make the bed and tidy up in the morning as part of our morning routine. As the day goes along, I will tidy up after each project I do, if I am working in here. Once a week, we dust and vacuum. It is so fast when all the surfaces are clear of clutter!
DH has a nice wood organizer box on top of our dressing chest. It holds his personal small stuff, including wallet, keys, phone, wedding ring, watch, money clip, etc. It is right next to our clock CD radio, which has a built-in charging station for iPods and iPhones, etc. It came with 3-4 inserts for charging those various items. I keep one in the slot and the other one we use on DH's box and the others inside his box. I have two CDs I like to use for meditation. One is in the CD portion and the other is in the prettiest case. LOL (I gave away the other case.) I switch off and the one CD case is neatly arranged in an otherwise empty spot. It is convenient for DH to empty his pockets in our bedroom because he generally changes clothes after work (from the hooks) and he enjoys a few minutes to himself when he first gets home.
I, however, am always running in and out of the house during the day and would seriously dislike having to go upstairs to the back of the house every time to get my belongings. I walk most places, but drive sometimes. I need different items for different activities and prefer to carry the least possible. We have a small "pub mirror" next to our front door. In addition to the mirror, it has a shelf and three pegs. I have my various keys and favorite hat on the hooks/pegs (single house key for walks; house/mail/car keys for drives; dad's house key; and whichever neighbor's house/mail key we're housesitting/petsitting). If I am using a purse of some sort, then it is usually small enough to hang from a peg. The shelf is very small, but holds lip balm, lipstick/gloss, a piece or two of outgoing mail, and my prescription sunglasses, which I swap for my regular glasses and return immediately. Next to this space is a tall Ikea bookcase with doors on the bottom. The first open shelf has an organizer basket closest to the door and holds coupons, gift cards, digital camera, small tripod, Chico bags (2), small tape measure, membership cards, small wallet-type insert, small flashlight, etc...all outgoing type things. There is space behind it, so we tuck two paper lunch bags back there to hold batteries and lightbulbs for recycling. They cannot be seen, but we know they are there. If I had the organizer pushed back, then "stuff" would accumulate in front of it (or the paper bags would obscure the organizer and make it unfriendly to use). The bottom step of the staircase is our holding zone for bigger outgoing items, such as a stack of library books/videos or a bag of returns to the store. In front of the tall bookcase is the spot for bigger outgoing items, such as a box or camping gear or luggage. Having the doors on the bottom of the bookcase means we don't leave these types of things for long because we cannot get into the bookcase! The bottom of the stairs can only hold so much before maneuvering becomes difficult. This is all by design!!!
Our very small coat closet is under the stairs and somewhat awkward since it is not close to the door. There is no other place for jackets and such, so we make do. I added two sets of hooks (one on each side of the small closet). One side holds our "go bag" and other outside play stuff that can hang (jump ropes, for example) and the other side holds the canvas bags that are not in our cars. I leave from the house multiple times a day and 90% of the time I am walking the opposite direction from our parking area (townhomes where monkeys designed the parking lots). I often clip a Chico bag to my purse or belt loop for the return, but many times I am taking stuff with me too. Having canvas bags in so many places can get tedious, but it is the only way we remember to use them.
