Hi Anne from Sebago!
This will be our 6th year visiting the mid-coast region and I CANNOT begin to tell you how much we enjoy and look forward to it. The two shops I visited for the first time

last year are both in Camden. Unique One has a nice selection (in the back) and they sell clothing in the front. The other is Stitchery Square and has other needlework items aside from yarn.
I was looking at the Camden Tourist website and saw an item about a spinnery in Hope called
Hope Spinnery - about 8 miles away from Camden it looks like.
My kids are spending a few weeks at summer camp and visiting them is what brings us up there. I am certain we'll continue to visit long after their camp days are behind them!! If you come across any other great places along coastal rt. 1, let me know!!
We haven't explored much of the southern coast, though we had a very nice lunch last year in York on our way back to reality. Hope you have a great summer and don't let any obnoxious tourists (myself, of course excluded from that designation) bug you too much!!
Lynn
