Michael's closeout sale on flat china for mosaics
Michaels sells these packets of 50 square inches of flat china for mosaics (pre-broken). They normally sell for $7/pack and have a closeout sale at $2/pack. THey have packs like the top left and top right at this link.
I like them much better than real china (no bumps to deal with) but they are normally pricier so I thought I would share this sale information.
