Make a Custom Flexible Dressform Arm

Before I start on the instructions to create a custom arm for your personal sized dress-form a quick update on Wolf Dress-forms. Sadly the company is out of business and Peter Lappin of Male Pattern Boldness tells the story. Wolf forms occasionally show up at tag sales, store closings, on EBay or Craig’s List but they can command a hefty price. If you are lucky they can be purchased for around $200. Best of luck if you embark on a search.

I’m always looking for snippets of information as to the workings of couture ateliers. The film, Signe Chanel, shows an inside view of Chanel’s workrooms and I noticed that the mannequin arm is extremely soft and flexible. Not at all like the rigid arm form which came with one of my forms.

Pre Made ArmPre Made Attachment

This arm is very heavy and intended to be attached by tying the tapes around the neck. Unfortunately this never worked well and was difficult to insert into the garment sleeve. I’m including my pattern for a custom sleeve form as a printable pdf document. Hopefully I’ve formatted it correctly. This is my first attempt using Adobe Illustrator and have found the learning curve fairly steep. The pattern tiles are 7.5 x 10 inches so expect 1/2 inch margins all around if you are using US paper. It should also print out on A4 paper fine, just adjust the margins. Print out page 1 to check that the size box prints at 4″ x 4.”

Mannequin Sleeve

There are NO SEAM ALLOWANCES. I used cotton drill cloth for the two main arm pieces, cotton muslin for the oval armhole and wrist covers and cardboard to insert into the armhole/wrist covers.

Fabricsitch lines

I’ve traced the stitch lines in blue dashed lines and am adding 3/8 inch seam allowances. Transfer the vertical and horizontal balance lines also. I use washable marker. Notice the vertical line down the upper arm pivots at the elbow.

There is ease on the upper arm at the elbow point. If you try and match up the stitching lines there is excess fabric which needs to be eased in to create the elbow shape. Stitch the back seam first.

If your balance lines are slightly askew at the elbow, blend into a smooth line across the seam. The marks will dissolve with water after you topstitch the line. Press the seam open. I use a topstitching (has a larger eye) needle and two strands of black thread to trace the balance lines using a 3.5mm stitch length. There are three horizontal balance lines, one at the elbow, one at the underarm and another about 2 inches up from the underarm. Extend the upper balance line to cross both sleeve sections.

Close the remaining seam matching the stitched balance lines. Press open. Close the dart at the top of the sleeve. Cut the shoulder piece (looks like a shoulder pad) from drill cloth. It needs a seam on one side only. I serge the outer edge to prevent fraying. Using a 4.5m stitch, sew along the top of the sleeve. It will gather up slightly which is all you need. Don’t try and ease it like a set-in sleeve.

Clip within the seam allowance on the shoulder section. Mark the mid point and attach it to the arm, matching the mid point to the dart on the sleeve. Make sure you have right sides facing each other. It should look like this.

To stuff the sleeve I use soft polyester fleece. I cut a piece the length of the sleeve plus about 2 inches. Roll up the fleece, not too tightly, and gauge about how much is required to fill out you sleeve. I want the sleeve to be full but not tightly packed and stiff. The wrist and lower arm needs less fill than the upper arm so I shape the fleece like this. I’ve used about 30 inches an have cut off one corner so that the lower arm has less stuffing than the upper.

Cut Fleece

Begin rolling at the shorter end forming a soft cylinder which is fatter at one end. I safety pin a length of ribbon onto the slimmer (wrist) end, insert the ribbon through the top and pull it through. If you want more or less fill pull out the roll and adjust the amount of stuffing.

Rolling fleecePull through

Trim the fill at the armseye end leaving enough to fill out the top.

Fleece at top

Cut ovals from cardboard for the wrist and armseye covers. I use lighter weight muslin (the drill cloth is too stiff to gather) and add about 3/4 inch seam allowances. Stitch around the edges, insert the cardboard and pull the threads up to create the covers.

Cardboards

I place the armseye cover against my form and mark the shoulder seam point. Notice that I’ve angled it towards the front to better replicate my arm position. Human arms tend to fall slightly in front of center. Line up the wrist oval to simulate the wrist shape. Again wrists aren’t circular; they are wider when viewed from the top of the hand than the side.

Scye cover rotatedAttach Wrist

Hand sew the covers in place with a whip stitch. Your new arm can be attached with a few pins (I use flat head pins and push them at an angle to avoid snagging the garment). This pattern is for the right arm. If you would like two arms just flip the pieces and make a matching form for the left side. See how easily her arm bends and I’ve found this version much more workable than the premade ones.

CompletedBendable Arm

This will make a fairly slim arm. If your arms are larger and you want to adjust the pattern I would suggest this method. Trace the pattern onto your preferred paper and slash the upper and lower arm sections. I don’t cut up my master pattern until I’m happy with the changes. If the first alteration doesn’t work I haven’t destroyed the original and it’s much easier to start over.

Adjust

Divide the amount you want to adjust by 4 and spread the pattern sections by that amount. It doesn’t need to be the same for the entire length of the pattern. You might want an extra inch at the wrist and an extra 2 inches at the bicep. Overlap the sections if you need a smaller arm. Likewise the length, both above and below the elbow can be adjusted. The ovals for the armseye and wrist covers will need to be adjusted and I would just use trial and error. There is a mathematical formula for figuring out the circumference, long and short axis of an ellipse but you don’t want to see it. Anyone with a math background will understand! Enjoy.
