THE ENGLISH VERSION OF PATTERN IS BELOW THAT IN ITALIAN.

The Butterfly Cardy was designed as half-season sweater or at least to be worn on a t-shirt or a body for example in the evening
if the air should refresh suddenly . Deliberately it does not close completely.
If you would like to make it fully lockable, advise you to increasing some sts while running the purl row before the lace motif, taking into account that the motif is worked
on a multiple of 18 sts (so it must increase at least 18 sts) and opening button hole on the right side edge.
You can pick a bit ‘as you like, even changing the lace point … I have in mind some variants …
For little boys you can work as following.
Doings the reglan increases work the half front sts and then continue working on garter st only on the sts corresponding to the sleeve for about 60 irons
(and still up to the desired length … this is the convenience of this type of work!) and cast of the sleeve sts.
Continue working in garter st the back’s sts and then repeat the process explained to the other sleeve and work in garter st the other half front sts.
Then continue working in garter st only on the remained sts increasing some sts during the execution of the first row and continue to work to the desired length.
Remember to open the button hole on the left side.
Sew sleeves.
