This cost me 0$, these are all stuff I found in my home and you can find your one personal things and translate these ideas into your own. Or go to the dolar store and there are some pretty cute things and they are all pretty cheep and affordable.
I just drew this and it actually looks pretty good, the letters should be ombre but I totally messed up the f. Anyways I just drew this one a cardboard and hung it up on my door.
These were the Pumpkin Spice Marshmallows that I used to put in those cute orange bowls.
So this is how I did the spider, the first picture were my supplies, I took some styrofoam and cut it to the shape of two circles, one larger than the other. Than you have to paint them black. Cut of some orange pipes and bend them like in the picture below. Repeat this step 6 times.
Then I glued ( you can use hot glue gun or regular glue) the orange pipes that serve as legs of the spider, also glue the 2 circles to create a head and body. Then glue the two pompoms as eyes and you can then draw some dots in the center with a sharpie.
