Finally, adult-sized upcycled wool longjohns. Make your own in this DIY kit!

Transform a sweater into warm, breathable, luxurious long underwear. Wear the finished pants as a warm underlayer or show them off as leggings.

This 9-step sewing project can be completed with either a sewing machine or a serger. Suitable for a beginner sewer. Completed longjohns have elastic waistband and cuffed ankles.

Kit includes:
-full detailed instructions with colour pictures (PDF file)
-merino, cashmere, or wool/silk blend sweater (Sweater may be accented with reverse applique. Please indicate when ordering if you do NOT want this feature.)
-waistband in upcycled merino or cashmere (as close to the colour of the pant's body as possible)

Please note that these longjohns are made completely from an upcycled sweater. The instructions will show you how to reconstruct the sweater into pants, tailored to your size and fitted with an elastic waistband. Initial seams from the armhole of the sweater will sit just above the knee of the finished pants. Despite an unconventional pattern, the finished pants are remarkably comfortable and an economic way to indulge in warm wonderful wool.
