For those of you on a serious budget (like me) who want 12" x 12" square mirrors under your centerpieces, I got this idea from a former Knottie from my local board several months ago: Lowe's sells 6-packs of 12" x 12" square mirrors for only $8.98 a pack! Michael's and A.C. Moore sell the exact same size mirror for $7 each. Even with a 40% or 50% off coupon per mirror at Michael's or A.C. Moore, you still get a better deal with Lowe's!
