Guide for Seam Finishes

You have all of your supplies ready, you’ve adjusted your pattern, cut your fabric and you’re ready to start sewing. Before you sit down at the machine, have you thought about the best seam finish to use for your fabric? This post will help you to choose the best method to assure your seams are perfect.

Fabrics & Best Seam Finishes

Batik: Flat fell seam or sew with a plain seam and serge together
Batting: Butt the raw edges together and hand overcast with basting thread to get the width you need.
Beaded Fabric: Finish with a product like Great Seams as in Hong Kong finish. Eliminate facings. Finish the neck and armholes with bias silk charmeuse or line your garment, making the attachment at the neck and shoulders.
Boiled Wool: Sew seams and clip curves. Press seams open and top-stitch on each side from the right side using a wide double needle or top-stitch each side separately from 1/8” to 1/4” allowance from the seam. Trim to your top-stitching.
Brocade: Press seams open and overlock separately, even if lined. Use a Hong Kong finish with lightweight silk or bind separately with double fold bias.
Burnout: Finish with a narrow French seam.
Charmeuse: Use flat fell or French seam on serger.
Chiffon: Use a narrow French seam. On long vertical seams, sew with tiny zig-zag stitches to prevent drawing up.
Corduroy: Serge seams separately or flat fell the seams.
Crinkle: Sew with a tiny zig-zag.
Damask: Sew flat fell seams.
Denim: Sew a straight seam. Serge one seam allowance and trim the other without turning under. Overlap the serger seam allowance onto trimmed seam allowance and topstitch. This forms a fake flat fell seam that is less bulky.
Dupioni: Serged or traditional flat fell; serge and press open.
Faux Fur: None
Faux Leather: Use a fake flat fell seam or finger press open and top stitch from the right side, straddling the seam. Trim close to stitching.
Faux Suede: Lightweight ultra suede seams can be simply pressed open. Other faux suede’s can be top-stitched with a double needle or treated with a fake flat fell seam.
Flannel: Straight stitch or flat fell seam
Fleece: Sew with a straight seam and finger press open. Top-stitch or serge.

Gabardine: Press seam open and serge each side separately with a woolly nylon in lower looper; flat fell; or Hong Kong bound.
Georgeette: French seam.
Jersey: For lightweight knits, sew the seam, press to one side and top-stitch 1/4’ from seam. Trim extra fabric away. For invisible seams on wool jersey, zig-zag and press open.
Mudcloth: Flat fell or bind with double bias.
Rayon: Flat Fell or press open and serge.
Slinky: Four thread serge with Woolly Nylon in lower looper. Use differential feed if needed.
Sweater Knits: Stabilize horizontal seams and neckline using 1/4” clean elastic. Sew seams with small zig-zag then four thread serge. You can also sew with a lightening stitch and bind with Great Seams.
Tencel: Flat fell or press open and serge separately.
Velvet: Press open, pink or or serge separately.

Hemming Jeans – the Denim Blues

Perhaps you searched long and hard for the perfect fitting jeans, but alas, they’re too long! Or maybe you painstakingly created a custom pair and it’s time to hem them. Either way, you’re in the thick of it—literally!

The hem area of jeans can be up to eight layers thick, depending on how the side and inseams are constructed. Stitching through all of that thickness while maintaining straight, even stitches and not breaking the needle can be a challenge for any sewer, but here are some helpful hints to make the process easier.

Before you sew

Before you determine the length of your jeans, be sure to wash and dry them at least twice to allow the fabric to shrink. Nothing’s worse than meticulously hemming them and after the first wash, they’re ankle skimmers.

Try on the jeans with the shoes you plan to wear with them and pin-mark the desired finished length on both legs. Both legs aren’t always the exact same length.

Assemble the arsenal

Denim Needles

Having the proper tools to sew multiple denim thicknesses is a must. First, select a denim or jeans needle with a special tip and blade to cut through the fibers without deflecting (because of the tight weave) or breaking. Denim needles are made especially for sewing extra thick fabrics, and they’re available in sizes 70/10 to 110/18—the heavier the denim, the larger the needle size needed.

Topstitching

In addition, if you’re doing decorative topstitching to mimic the infamous Levi gold version, acquire a topstitching needle with a large eye and groove to accommodate jeans thread without shredding.

Denim Thread

Choose either an all-purpose or denim blue thread for stitching if you want a matching hem, or a heavier jeans thread if you prefer contrast seaming detail. Denim thread is a twist of multiple blue colors to mimic the looks of our favorite indigo fabric.

Hemming

Press up the hem at the desired length and trim the hem allowance, leaving about 1”. Press under ¼” along the upper hem edge, then ¾” forming a double hem. Pin in place.
If you need a bit of stability on lightweight denim, slip a narrow strip of fusible web into the hem area and press before stitching to firm up the edge.
Straight stitch along the upper folded edge using matching or contrasting thread. For more prominent stitching, use a straight stretch stitch.
On very heavy denim, serge the upper hem edge instead of folding it under to finish, and that will save one layer of thickness.

Height busters

The absolute hardest part of hemming jeans is going over those leg seams, but there are tools to help. Look for a Jean-a-ma-jig, Hump Jumper or Big Jig to help even out the raised area.

These tools are slipped under the presser foot on the ascent to the leg seam thickness to help keep the presser foot horizontal over the ridge and again on the other side to keep it from sliding off the raised area and making uneven stitches on the downward journey. And, they work on all machines.

For the neatest appearance, bring thread ends to the wrong side and tie them off instead of backstitching.
