I love yarn.
If you love yarn, consider shopping here:
http://www.fiberworks4yarn.com/ The owner is sweet and wonderful. Her giant clearance section has yarn at $3/skein. I'm talking Noro at $3/skein. It's huge. My sister's xmas gift went from a $50 project to $12 thanks to it. On top of being sweet and wonderful, she is nothing BUT helpful, friendly, VERY knowledgable- the woman KNOWS her yarn. How she can keep track of the enormous variety I don't know. I've never seen more yarn in one space in my entire life. The store is brimming with it.
She's open all week and has great hours. She's really close to most of us in MD:
17830 New Hampshire Ave The Alloway Building - Suite 101 Ashton MD 20861-3641
The shop is right before 108 on 650. If you knit and need yarn, you must visit her. She's wonderful. The regular prices are great too.
