There are lots of places to learn about needlework all over the 'net, and sometimes it's all a bit overwhelming. Enter Eglantine Stitchery's Resource page: http://eglantinestitchery.blogspot.com/p/cross-stitching-resources.html
Aurelia Eglantine has compiled some great tutorials and pamphlets that answer the tough questions, like how to change colors and skin tones; how to stitch fractionals, and the life expectancy of heirloom cross stitch gifts. There's a link to a stitch calculator, even a questionnaire that can help you decide if the cross stitch hobby is right for you. You'll find links to lots of other blogs there, too.
Stop by and say "hi" and become a follower of this wonderfully helpful blog.
