Millersburg and berlin are a bit of a drive from the Cleveland area but well worth the trip. It makes a nice daytrip if you have the time. from where you will be you should be able to visit Polkadot Pincushion in richfield or Little Red Quilthouse in Granger. if you want to go a bit farther,A Piece in Time in Akron is also nice.

If you do get time to take the trip down to holmes county, be sure to go to Millers dry goods in charm. it's worth the drive all by itself.
