A vintage knitting pattern for a child's lacy stitch v-neck sweater and with instructions to knit in 4 sizes.
To fit: 24", 26", 28", 30" chest.
The original yarn used was Wendy Monaco with a tension of 7 sts and 12 rows to 5 cm, over the pattern stitch, and using 5.5 mm needles.
I believe that Monaco was an aran weight yarn, so you could try a modern aran weight yarn and work a tension square, changing the needle size if necessary to get the correct tension.
The pattern leaflet is in good condition.
