Another market venue that you might want to check out is all of the local farmer's markets. There's a really good one in Vancouver, WA, which is just across the river from PDX. Also Gresham and Hillsboro. I've sold at all three of these places and they are friendly and open to new sellers. Salem also has a Wednesday market, which I haven't tried selling at, but it always seems to be really busy downtown. I will post shows as I remember them. There are lots of them.
And your are right, ForestGreen. Rickreall is a really good craft fair, although it's kind of hard to get into.
In some cases, you have to be very careful. If it comes from someplace like Disney, they will sue you for it.
I think that if you buy the pattern, and then significantly alter it, it's yours. In the case of beaded bowls, if you make it just like you are seeing it in a picture, then it's no good. But if you use the tutorial just for inspiration, and make your own design, then it should be yours to sell.
I think most crafters try everything at least once in their lifetime. I started crafting as a child, encouraged by my mother, who is the crafter's crafter (I am constantly in awe of the many things she makes from nothing but junk).
We did paper crafts with my mom, woodworking with my dad, and when the bookmobile came around, we sucked up every crafting book available. I have tried leather work, paper crafts, metal work (copper jewelry), plaster crafting, woodwork, woodburning, clay modeling and crocheting.
I am currently doing woodworking, (my passion), photography and cards, and recycling art, which is quickly becoming an obsession. Someday I hope to learn tatting.
The floppy disk is actually 3 1/2 inches square, so I cut the sheet cork 3 1/4 inches square and glued it in the middle of the back side of the floppy disk. After the glue dried, I put glue around the outside of each of the disks, so that the glue overlaps onto the cork. Then I just stuck them together, using rubber bands to hold them until the glue dried. It dries so hard that the box is rigid. This is kind of a long-winded explanation, but I hope it makes sense.
I ended up making three of them, one is all black, one is black and white, and one is red, blue, green and gray. Good luck with it.
