this is a pattern that evolved from another project - I have made two in different sizes since! Worked using two strands held together - makes a cute laptop sleeve/sweater for your computer (makes a cute pillow too!) General sizing instructions for different size computers added and direction in modifying the pattern motifs for your taste (lots of room to play if you want!) I would say this is advanced beginner - diamond-y motifs can be confusing at first I think. Stitches needed are sc, dc, fpdc, popcorn, hdc….nothing to hard. Great gift item for christmas!
