Hi dchaney! I thought you were a newbie but since I checked and you've only posted twice, this post and one in 2009, I know now you are a lurker.-lol- Anyway, I say welcome because I just saw this post and show us more of what you're doing.
I have done a few fairs, years ago, but I make/sew my own items. I mostly now make for my bus trips and desperately need new ideas.
I do have a handkerchief some gave me from embroiderthis.com and some double seat panties. The quality looks good on these. Maybe you could find something there. Good luck hunting and selling!-Toogie
ThreadArt has a sale on blanks. Also check out selling at craft shows.
In many place you will have to have a county or state business license and report and pay taxes monthly or quarterly. Craft fairs will occasionally offer a free booth for a donation, but usually will be upwards of $60, rain or shine, turnout or not. You want all craft, not an event that is mostly about selling a barbecue plate or hearing the local band or seeing the cheerleaders - no one will be shopping your booth during lunch or performances and often the festival that was scheduled to last till 4:00 dwindles away after everyone eats lunch. Poof - there goes your profit. It helps to go to high attendance festivals, although their booths can be quite pricy.
Embroider This is a site that sells Blanks.
A lot of things you could actually make yourself for far less that way you can be more competitive with prices.
Tote Bags
Zipper Purses
Baby Bibs
Aprons
That's just a few that come to mind.
Michael's for onesies, t shirts and tote bags. Dollar General for odd things once in a while, like the Christmas shapes placemats that can be embroidered on. Pier 1 and World Market (retail stores) for nice cotton napkins and placemats. Wal-Mart for onesies and baby bibs and sometimes their blankets, when plain. Also, check out sewingmachine.com for great supplies and oddments.
Here in Alabama, I figure if my blank costs more than $3, it's going to be a hard sell at a craft show. People don't realize the time and supplies involved in embroidery.
If you have a state business license try contacting some wholesale suppliers like SanMar, AlphaBroder, Augusta, TSC Apparel. Sales tax will be paid on your sales, not your purchases.
Also, keep all your business supplies separate from your personal supplies; by doing this, all supplies purchased for your business will be deductible. A good CPA can be very helpful in getting you started or giving advice in how to keep more of your own money.
Thanks for adding your bit of the Universe - asterixsew - UK
Knowing what part of the world you live might help. I get a lot of my supplies from Amazon
