Can she use a sewing machine? There are lots of postings for little felt monsters on this site. They seem pretty easy and fast and appropriate for a kids' arts and craft show. Also, handmade cards. Also, this: http://www.craftster.org/forum/index.php?board=18;action=display;threadid=722 and use the melted hot-glue-gun glue stick method. There are a ton of interesting things that she could use for the covers for the notebooks. Someone mentioned candles. She could also decoupage votive candle holders with tissue paper. Very fast and easy. This is a long post. I'll stop. Good luck!
Amalia, I would suggest asking the people at the fabric store. They are usually pretty knowlegable. Look for a light to medium weight interfacing (I used a light weight interfacing in my bag above - enough to hold a shape and stand on its own, not heavy enough to not sag though). It sometimes comes in packages ( at a craft store, for example), so it's easier to read specifically what you are getting (as opposed to buying it by the yard). Good luck.
Hi, A while ago, I knitted and felted this bag for the intention of using it as a knitting bag. It holds a lot of stuff and I made a little knitting needle carrying case to carry around, um... knitting needles and the like. The pattern is pretty simple. More or less, cast on 100 or so stiches on size 13 circular needles and knit in the round for however many inches you want. Towards the top, add in a fun novelty yarn (mine is Fun Fur from Lion Brand) while decreasing the number of stiches so the opening is smaller than the bottom. Cast off, sew the seam together at the bottom and sew across the points to make it square bottomed, add the handles, and then felt. The bag is great. I got the pattern from Fiber Trends.
Like NynaeveAS, I saw this product in a magazine and thought that I could make it. So I did, with a few differences than NynaeveAS'. I used cotton for my material instead of vinyl and used interfacing between them. I also did two rows of stiching between the pockets to make them a little stronger. And finally I added some piping to the top of the pockets to protect it from the wear and tear of taking things in and out of them.
I'll work on posting pictures so that it does't look so... bad.
