Gathering and sleeve easing both shorten an edge temporarily, but they create different results. Gathering distributes visible fullness. Easing contracts a sleeve top to fit an armhole without forming gathers. Janome’s Continental M7 Professional instruction book describes both operations; use its steps only with that model and the matching manual.

Make and attach gathers#

For the M7 gathering procedure, leave thread tails about 10 cm long under and behind the foot. Sew two straight-stitch preparation rows 0.6 cm apart. The manual does not give a numeric length or tension for these gathering rows, so do not use the joining seam’s displayed defaults for them. Knot the thread ends at the start, pull the bobbin threads to draw up the fabric, then knot the ends and distribute the fullness evenly.

To join the gathered piece, exit the sewing application and select the M7’s U1 straight stitch. Janome displays default tension 3.8 and stitch length 2.40 for this attachment seam. Sew between the preparation rows, then remove those temporary rows. These values apply to the joining seam in the M7 manual; they are not settings for creating the gathers.

Ease a sleeve top#

For sleeve easing, the M7 manual calls for two preparation lines 3 mm apart along the sleeve-top edge. Pull the bobbin threads carefully to contract the edge until it matches the armhole size. The intent is a smooth fit, not visible gathers in the sleeve cap. The excerpt does not identify a stitch number or numeric settings for these easing lines, so keep those controls within the exact manual’s guidance rather than borrowing the gathering attachment defaults.

Test both operations on a matching fabric scrap. Check that the amount of fullness is distributed as intended and that the sleeve edge can be eased to the pattern’s armhole without bunching. This source does not establish a universal ease ratio, preparation-row setting, or guaranteed garment fit. Other Janome models may use different applications and controls. For an ordinary seam choice, see the straight, zigzag, and stretch stitch guide.
