I live in the Central Valley in California so our weather isn't cold enough they say for the stores to carry the lavendar or pink foam to use for tombstones and such. Last year Home Depot had some in 2 by 2 squares at almost 6 dollars per panel. They do not have any this year at any I have checked. Any ideas on what else I can use or where I can order some without shipping killing me? The sites I have looked at so far say not available online. I plan to use Terra's technique for the stones and want to make her Beloved.
