Thanks everyone. Patti :lol:
Esq - the QAYG is very easy, the only fiddly bit is blindstitching the folded edges of the strips on the back but I actually quite enjoy that part - it's like sewing down a binding. For a little thing thing like this QAYG isn't really necessary but the technique just fitted with the Quilt As You Piece aspect of the string block. I'm already planning another one where the strings are different sizes and angles to create a heart. Well OK I'm getting all soppy and romantic - as Katrine said - Valentine's Day is approaching! ;-)
