HARRINGTON, Maine — The eastern Maine wreath company that started the annual tradition of placing thousands of wreaths on grave sites at Arlington National Cemetery is opening its doors to teach people how to make their own wreaths.

Residents this weekend are invited to Worcester Wreath Co. in Harrington, where they can learn how to make a Christmas wreath and take home their creation free of charge. The wreath-making will take place from 10 a.m. to 4 p.m. on Saturday and Sunday.

Morrill and Karen Worcester say they offering wreath-making instructions to give thanks to Mainers for their support of the Wreaths Across America program, which this year placed some 90,000 wreaths at Arlington National Cemetery.

Morrill Worcester began the tradition 20 years ago.
