"The Handicrafts best fitted for children under nine seem to me to be chair-caning, carton-work, basket-work, Smyrna rugs, Japanese curtains, carving in cork, samplers on coarse canvas showing a variety of stitches, easy needlework, knitting (big needles and wool), etc."
~Charlotte Mason Volume 1 Page 315
Here are the basic you will want for a sewing box:
Fabric (cotton and felt are the easiest to start with)
Needles (needles with larger eyes are better for little hands to thread)
Pins on a cute pincusion (pins with round plastic heads are easiest for little hands)
Safety pins (they are sometimes easier to use than straight pins
Scissors (they should be sharp, so be sure to supervise)
Cute measuring tape
Put all these items together in a cute sewing box and you are set.
You can also include instructions for the easy felt bear I have posted. The link to the post is here. I would love to post photos of your sewing boxes or bears you have sewn using my instructions on this blog, so feel free to email me photos or links to your photos at firstname.lastname@example.org.
I can usually find little travel sewing kits at my local DollarTree store, which has assorted thread, pins, needles, and buttons. Walmart also has little sewing kits already put together. Or here are some links to get you started.
You can even buy felt on Amazon.com!
And I still have quite a few Hearts and Trees Winter Themed Art, Handicraft and Nature Study Kits available, so be sure to check out the post here if you haven't already done so!
