I made this with the intention of keeping the sun off Betty. Have we had any sun? Nope.
It's a made up pattern that closely copies a favourite top of hers. I simply drew around the bodice pieces, enlarging them to make a template. The sleeves are slightly tapering rectangles with elasticated cuffs, and the main body is also two rectangles with gathering at the centre. I made my own bias binding with a rather handy little gadget . All we need now is some sun!
