Im decluttering right now! We are doing item by item, like this:
Clothes
Shoes
Bags
Entertainment items (books, cds and DVDs)
Toys
Toiletries and cleaning products
Makeup
Kitchen appliances
Sentimental pieces
We started on clothes. Take anything obviously out of season from your wardrobe and put it in those vacuum bags. Then, turn all the hangers round. Go back in 6 weeks, anything that still has a hanger the wrong way gets ditched (except occasional wear items like wedding outfits)
Then, go through your occasionally worn items. Only keep what you will definitely wear again. Get rid of anything that doesnt fit or doesnt make you feel good.
For clothes, we take things to one of those cash for clothes places. Anything which is good quality or expensive gets sold (I do this with my going out dresses)
Get rid of all DVDs and get Netflix. Music magpie take old DVDs. Back up all cds onto the computer and get rid of them too. Donate books to a charity shop.
Then do toys. For this, I divided her toys into categories (music toys, art supplies, construction toys, imaginative play, and so on) and then chucked anything that was broken - those went to cash for clothes too. Then, if she had duplicates or similar items,she chose her favourite. The other one was set aside. I then found a specific place for each item, not just a generic toy box as I find things dont get played with that way.
She ended up with a huge bundle which I sold and gave her the money in her piggy bank.
For craft supplies, I put everything in one of those plastic 3 drawer chest things inside her wardrobe. She has a little craft table with pots on it, each pot has a few pencils or crayons - one of each colour - so she can still use them properly but there isnt a sea of crayons. She gets one colouring book and one drawing pad at a time. Other craft things like tissue paper, glue, glitter and all the messy things stay in their drawers until they are needed, then I get them out! Im going to stop buying so much stuff.
I got rid of everything we didnt need in our kitchen. Things like the baby blender, our food processor, spiraliser, toastie machine all got sold. I even ditched the microwave because it wasnt working properly.
For kitchen clutter, I meal plan around what we actually have in the house and only buy what we really need. We had ridiculous amounts of things in the cupboard which would never get used.
Im putting all photos, cards etc in scrapbooks and using he space made from ditching DVDs and cds to store them.
