I tried to buy an infinity scarf...they were sold out! Look really easy to make. Instead of knitting, maybe just a piece of fabric with finished edges, sewn together on the ends.

Christmas tree ornaments or card holders made from painted clothes pins...snowmen, Christmas trees, reindeer, Santa. These are from Container Store and a bit more elaborate, but you could simplify the design.

Version made with a tootsie-type pop.

Mason jar scenes...more expensive materials, but still easy to make.

I've made snow globes out of mason jars like those. It was a great project with the littles.

Heat packs are great. I use flax seeds in mine

bought several jig saw puzzles. spray painted pieces... green, red, gold silver. cut rings of nice heavy cardboard... corrugated stuff from boxes. kids glued painted puzzle pieces all over until you couldn't see any cardboard. very cute wreath.

Old sheet music, music lesson book, or any other book that is no longer used. Tear out the pages. Roll each one up into a roll of paper about the circumference of your finger. Stack them into a pyramid, glue them in place, tie a pretty ribbon around it and glue on seasonal decorations such as berries, pine and pine cones, flowers, wheat, etc. Pretty on a table.

pinterest has tons of ideas just go there and do a search for quick simple crafts. Button art projects are super easy and sell well. Modge Podge projects are easy and neat. I did little jars covered with fall colored leaves and put little candles in them.

I don't know how old your grandkids so not sure of a skill level. This may be too advanced. Wreaths for the front door are popular around here.

Many years ago, a close friend gave me a darling necklace made of unfinished wooden flat clothes pegs and I've copied it dozens of times for cute gifts.

The model I've attached is only an example. I use smaller felt ears, tiny jingle bells as well as red beads to separate the pins.

You just need a drill to make the holes, a glue gun or quick stick glue, googly eyes, tiny pompoms for noses (8 black and 1 red), and a sheet of felt from which to cut the ears. Jingle bells, colored beads, and ribbon can be chosen according to your preferences.

My little sprites and I have been creating these for three years. They like to give the deluxe models to their teachers and smaller versions for their little friends.

Reindeer necklace example

All great. ideas,thank you.Grands are 10,11 & 12

Google wooden spoon reindeer..........years ago I made the standing one (five spoons) small can of stain....you could do this ahead of time. After that, just need felt and glue. There's an assortment of different reindeer ideas.....Spoons can be bought at Michaels pretty cheaply. Also check out wooden spoon reindeer on Pinterest.

You could make sock snowmen. You can get a pair of socks at the Dollar Tree for a dollar. Lots of videos on how to make them. No sewing involved.

We did these and sold them at our garden club sale. The picture frames were very popular. We got old picture frames at goodwill, since you cover them with buttons it does not matter what they look like.

I bought a wooden monogram letter at Walmart in the craft department and covered it then framed it. I got one of a Fleur-de-lis that I did and it survived the flood, it's now in the motorhome.

Interesting ideas for sure...to be honest,I totally forgot about my Pinterest acct.....

Mason jars filled with soup mix. Just saw those are still popular...Walmart is selling them!

Cookie or soup mixes in a Mason Jar are fun to make as well.

This site has a ton of recipes for soups, cookies and more.

Mason Jar Mixes

They look so cute

Ah! Nicole, great minds think a like!!! My daughter likes to give these to her friends at work

I have done the jar kits, one that was very popular was the spiced tea mix that uses tang. It is so good and easy to make. I made up big batches and put in cute jars and added a tag with directions. Hot cocoa mix too. It's called friendship tea.

Raven, thanks for the memory. I used to make the spiced tea mixes a million years ago, forgot about them. They were tasty, we called it Russian tea.

The heat packs are great! You can use field corn, like I do, and you can get it at Pet Supplies Plus in their bulk food dispensers here for $1.49/#. If you are going to do a ton of them, you can go to the feed store and buy a 50# bag for around $8, I think. I know it isn't a lot. At the craft show I went to yesterday, they made the bags out of flannel or fleece, but I like to use denim or upholstery fabric. I like the heavier fabric, as it seems to protect more from the heat. When I give them as gifts, I like to make a pretty "pillow case" cover for them. I didn't pay attention to the prices on the ones at the show yesterday. They did have different sizes available. Another thought for you, I put "channels" in some of them, so the corn doesn't all bunch at the bottom or ends when you put them around your neck or on your back.

Also like the idea of the mixes in jars.

How old are your grands? Pinterest has lots of rubber stamp card ideas. I bought some ready made guy cards at the show yesterday 6/$12, nicely done, with envelopes. There are directions for making post it note covers with card stock. If the kids are younger, you can do the cutting and scoring, and they can fold and decorated. These would be nice office type gifts.

What type of craft fair are you doing? Where are you selling... school, fundraiser, big event, etc.?

I've only done two shows several years ago. My experience was that people liked inexpensive, unique ideas. It's ok to use an old idea, but put a spin on it so it's different.

Are you allowed to sell the mixes in jars? Or are you getting into something that requires a commercial kitchen and a permit?

kids are 10,11&12....just a Christmas craft type sale-small town....we went yesterday to one in the little village here-lots of the stuff in a mason jar type of stuff(No permits req'd)a lot of knitted items,and a few wreath type tables.

We always have a wknd or 2 to do some crafts-this year they want to be able to do some stuff to sell(possibly)

Then the post it note covers would be perfect. You could also find the little calendars that are the same size. the covers look like matchbook covers.

-Bath bombs

-Christmas gift tags or package decorations that would add instant cheeriness to an otherwise bland present.

-zipper pulls for coats or backpack

-anything snowman I love the bobber snowmen and snowmen made from recycled random things.

Adellabedella, those are great ideas!

Agreed Tami-all fantastic ideas..thanks again
