Need help actually ideas about what to do with these brackets?

Remove all the hanging baskets and plant some evergreen shrubs, such as boxwood, upright cedars, etc. as they will hide and "soften" the foundation of your house and also hide the brackets that you say you can't remove. Then have a nice planter, pot or urn at the front entrance filled with flowers to add some color. If you like and go with my idea, make sure the front bed (where the shrubs will go) is not too skimpy but a fairly deep bed. If the soil is sparse and meagre looking, amend the soil with more good quality soil from a reputable garden centre. It pays off in healthy shrubs and plants.

Get a piece of board that will fit across the top of your brackets with a little bit extended on each side. Cut holes in the board that are large enough for a flower pot to sit in. mount the board across the top of the brackets, using screws to attach it and hold it in place. Add the flower pots into the holes. Similar to the picture below...but with the board mounted on your brackets instead of attached to a shelf.

Why are your hanging baskets failing?? Is it the plants you are choosing??? They recommend a "thriller, filler and spiller" when making hanging baskets but you also have to keep in mind your weather conditions AND your availability to care for them. Try a more drought tolerant flower such as a geranium which has many colors, can become quite bushy, will re bloom all summer with occassional deadheading and as an added plus acts as a mild mosquito repellent. As an extra tip to save on watering place a baby diaper open, plastic side down in the pot for water retention --- plants will thank you.

How about hanging a shelf on them and displaying something? or making a small herb garden on them?

Maybe a shelf with solar lights spaced across the length.

Put a board across and use it like you would a Mantle in the house, display some pretty Pots, figurines, Garden gnomes, Fairy Garden in flatter pots etc.. or just some vine plants.. You should be able to unscrew the brackets, then just fill the holes with silicone caulking, and then you can paint over the holes.. You can always put some medalions over the holes for some interest..?

Use the brackets as a base for stringing wire or string for a makeshift trellis and plant climbing rose or clematis or morning glory in the space. Just make sure whatever climber you choose is appropriate for the amount of sun this spot gets....I suspect that your hanging baskets are getting too much sun/not enough water and that's why they're not working out for you. Planting directly into the soil with the correct plants should help.

Put a board across them and potted plants on top. Or if you want them gone, but can't remove them (why not??), you could cut them off at the elbow and paint to match the siding.

Thanks for the great suggestions, will post a picture after I make some changes!

Put a board up and make a shelf. Then just put decorative things on it. Plant something under the shelf that loves shade. Or box in the whole space and make it a storage area.

Use them as bird feeders.

You can cut the overhang part off and maybe try to cover the part screwed into the house with some sort of decorative wood piece, or rock.
