Elsa's cape only needs three pattern pieces. I'm going to use one of the pattern pieces right from the same pattern all the other pieces have come from, (read previous blogs on making this dress, part 1, part 2 and part 3) but two of the pieces you will have to make yourself. But don't worry I'm going to give LOTS of guidance.
Materials needed are: the cape fabric, a little bit of interfacing and a nice hook closure for the neck.
Below are 1" grid diagrams to make a pattern for the large main cape piece in three size ranges, the same as the pattern we've been using.
Again, I'm giving these diagrams as jpegs and as Word documents. The adult size and the girl size are on two sheets and need to be joined. The child size fits on one sheet.
I would have just given a diagram with measurements to draw out, but that subtle up and down curve at the top of the cape is really important so it hangs correctly over the shoulder.
This pattern piece will be HUGE if the entire thing is made. I recommend just making the upper part and using a tape measure or yard stick to get the dimensions for the lower part.
To make the band collar that fits this, first draw on the stitching lines, 5/8" in from the cutting line.
So this is what you should have ... 2 large main cape pieces, 2 smaller upper cape pieces, 2 collar pieces and one collar piece cut from interfacing.
Tomorrow ... the sewing.
