Secondhand sweaters are exellent material for clothing reconstruction projects. Used sweaters are easy to sew with a sewingmachine and a suitable material for beginners.
The patterns are also easy to make from your old favorite clothing. This reconstruction is made from copying the pattern from an old jersey dress/tunic that I had, but you can aply the same technique to make one from an old hoodie or cardigan.
Ok, back to this reconstruction..
After tracing the pattern outlines, you will draw the lightning pattern. First make two diagonal lines deviding the pattern to three parts. Then again each piece into three parts. NUMBER EACH PIECE in a logical order. This will help you keep the pieces in order while sewing.
I have also marked which pieces have to be cut from the edges of the sweaters (egdes don´t fray) with short rib-like lines.
Repeat on the back pattern piece.
Here I´ve layed down the lightning-pieces (pattern nros 2, 5, 8) on the contrast colored sweater. Then place and cut the rest of the pieces. First find a place for the pieces that have rib-markings, they need to be cut from sweater hem or sleeve rib.
It does not matter which way the pattern piece is on the sweater. Anyway you are able to cut the pieces out is ok.
Stretch the pieces by pinning them on to your ironing board. As you can see they can be stretched almost double their original width. Give the pieces maximum hot steam (or press them using a pressing towel and maximum hot iron). Let dry for 15 min while stretched. The pieces are ready when they do not return to their original shape after the pins are removed.
