Pattern Review: Forest And Thread, It Takes Two

Threads #229, Spring 2025

Modern Warm-up Suit

(ForestandThread.com)

Skill level

Sewing this ensemble is moderately time-consuming, but not difficult if you follow the instructions carefully. The most challenging part of the project is sewing the curved seams.

Size range and fitting

Sized XXS to 8X for busts 29 inches to 61 inches, waists 22 inches to 55 inches and hips 33 inches to 66 inches. Available in two multisize PDFs, the warm-up suit’s B-Block is for sizes XXS to 1X and the D-block for sizes XXL to 8X. It is drafted for a 5-foot 8-inch person. The pieces are intentionally roomy.

Fabrics

Lightweight wovens weighing less than 10 ounces per square yard are recommended. Knit fabrics are also suitable, though you may want to size down the pattern. Select plain woven fabric, twill, textured linen, cotton, viscose, or Tencel. Knit choices include French terry, sweatshirt fleece, jersey cotton, bamboo, wool, or Tencel.

Style and sewing details

This two-piece warm-up suit has a unique look with asymmetrical curved seams, highlighted by contrast fabrics. The pull-on, elastic-waist pants echo the design lines of the jacket. They have diagonal side seam pockets and a straight-leg silhouette.

• The zip-front jacket has a standup collar, dropped shoulders, front and back yokes, and diagonal front seams with oversized pockets.

• The hemline is cinched with drawstrings tied at the sides. Several ideas are listed on what to use for unique drawstrings. The sleeve hems are finished with 1-3/8-inch-wide elastic.

• The style lines result in many pattern pieces. Most sections are cut on a single layer so be sure they are laid in the proper direction. Keep the pattern pinned to the cut fabric until the piece is used.

• There are plenty of notches and match points for easy assembly.

• The sewing instructions read like a mini book. They are detailed, showing illustrations for each step. There is even a comprehensive section on sewing curved seams, needle and thread choice, seam finishes, as well as sewing with knits.   

• Our seamstress recommends that, when doing the curved piecing, staystitch the straighter seam, clip it, and then, for accuracy, sew with the staystitched seam on top.
