Thank you for the compliment
There are several good free blackwork pattern sites on the 'net. I have used patterns off of this site: http://www.blackworkarchives.com/bw_flwrs.html
The butterfly came from this site: http://www.angelfire.com/band/samplers/osanna4.html
Blackwork is pretty much just outlining a design with double running stitch or backstitch.
Here is a site with brief instructions: http://snipurl.com/extn
If you want your design to be reversible and show the same on both sides of your fabric, you would use the double running stitch. If you do not care because the back of your work will not be seen, you could use the backstitch. I have not yet been able to get the hang of making my designs reversible, but if no one can see the back, who cares?
By the bye, I would love it if someone would tell me how to change webpage links into my own words like I have seen in other posts.
