The blue set below I have just finished. It is from the Sirdar Bonnie Baby booklet 212 and has loads of lovely sets in, including cardigans, leggings, booties etc so I can see me going to town with this booklet once I know what colours my daughter would like. The yarn is Phildar Luxe.
The green set below is vintage. I made this set for my son to come home from hospital in 15 years ago. He has grown a bit since then : ) The pattern is a complete boy and girl layette insert from Womans Weekly in 1981 and was printed when Princess Diana announced she was expecting her first child. I think it is called 'Fit for a Prince or Princess' and I still have the pattern in the loft. Again, the yarn is Pildar luxe.
