I do garage sales as part of my business.
Remember you are doing this, no so much to make money as to GET RID of this stuff. They are paying you to take it away.. If they do not buy it, you will have to deal with disposing of it. I would rather get something than nothing.
I have my husband hang a long rod from our carport, But the ladder thing works. for hanging clothing.
Do not do the group of books,. Except, childrens books. adult books, hard bound and paper back,, do not even organize them..
People that want books, know what they want.. It is not worth the effort.
Since we have a huge resale book company down here, we only get $1.00 for hard backs and .50 for paper backs. The exception is children's hard bound books. They can sell for a bit more. You can just place them on a table with the spines facing up.
Clothing is best if it all one price.. Example, Mens Dress shirts or collared shirts You decide if they are name brand and in excellent condition $5.00 each, but take $2.00
Tshirts all 50 cents
Dresses, depending on condition and name Brand.. $10.. but take $3.00 the last day to get rid of them.
I tie together, groups of kitchen utensils, I use cheap curly ribbon
I use cheap ziplock bags for groups of odd items. Small toys, Odd and end Greeting cards that have never been used, odd and end ribbons, bows, samples of bath creams, shampoos.. old christmas ornaments, broken jewelry, pairs of socks, Partially used jars of spices, envelopes of soups, oatmeal.. etc..
Partially used rolls of gift wrap paper can be tied together with curly ribbon, ,
I fold up sets of old towels.. Or I will fold 3 to 4 wash clothes and tie a ribbon around them.
I really trey to have tables. I borrow or I rent them.. I set them up the night before and that morning I just unload the boxes of stuff I have prepped.
Kitchen stuff, Children clothing, Mens clothing, womens, clothing, Decorative stuff. Vases, clocks, lamps.. Bathroom stiff, Christmas and holiday stuff. all of these items have their own area on a table or in boxes., You can even turn boxes over and put boards on them. to turn them into tables.
People do not like bending over to look at things on the ground. It makes it not look important. I usually continually place items on tables as things are sold..
I set up furniture together in one area. I make it look cute with a lamp, a rug, whatever.. Sometimes, people will purchase all of it.
Make sure if you are selling things that need to be plugged in you have at least an extension cord. I use a multiplug so several things can be plugged in at once.
