Homecaregiver - Patsy - There really isn't a sign up. I hope you join us and try the blocks!!
It is an interesting design and can be done in reproduction fabrics to very modern.
The blocks are part of a "sew along" on one of Barbara Brackman's blogs called "Material Culture". She gives a block each Saturday along with historical background on each of Queen Victoria's children. This week it was Block 7 - There are links in the right margin for each of the blocks. There are 9 blocks plus a border.
