Frequently asked questions
How much room does size S give a 90 cm bust?
Its finished chest is 112 cm, giving 22 cm of positive ease. The finished measurements already include this room.
Are Petra Jacket’s bands simple ribbing?
The front plackets are worked in double knitting, followed by a ribbed collar. These finishing techniques contribute to the designer’s difficulty rating of 4 out of 5.
How many buttons does the jacket need?
The materials list specifies five buttons measuring 18–20 mm, rather than the three 15 mm buttons used for Petra Polo.
Does Double Sunday need a mohair companion for Petra Jacket?
No. Use one strand of Double Sunday on its own. The table gives equivalent-metre estimates based on the original single-strand yarn option; check the 18-stitch × 26-row gauge after washing and blocking.
