Pins and needles in my right hand, also painfull.

Do you mean the Brother Innov-is 1250D embroidery machine? Insert your twin needle. Follow the normal directions for threading the upper thread and manually place this thread through the eye of the left-hand needle from front to back. For the right hand needle, insert the extra spool pin in the bobbin winder shaft. It gets put on perpendicular to the shaft. Swing down the spool pin so that it is horizontal, pointing towards the needle bar. Place another spool of thread on this spool pin and secure it with the appropriate-sized spool cap. The thread should come off the top front of the spool. Follow the threading directions for the upper thread from step 8 (the thread guide cover) through step 10. Do not run this second thread through the needle bar thread guide. Manually thread the right hand needle eye. Make sure to use the zig-zag foot with the twin needle.

The directions for threading the machine when the twin needle installed is on page 36-37 (pages 38-39 of the PDF) of the manual. The manual is available from Brother support on the product page: http://www.brother-usa.com/support/modelinfo.aspx?R3ModelID=NV1250D . The direct link to the manual is currently: http://www.brother-usa.com/VirData/Content/en-US/HAD/Consumer/UsersManual/UM_Innov_%c3%ads%201250D_EN_2825.PDF .

I hope this helps.

hi Frederick.
Paresthesia. This is the medical term for the annoying and sometimes painful tingling, numbness, and "pins and needles" sensations that can sometimes come from diabetes. ... The cause of our tingling and numbness from diabetes is usually peripheral neuropathy, or nerve damage in the arms, legs, hands, and feet.16 Dec 2014

Get Rid of Pins and Needles in Your Hands by Moving Your Head. That tingling feeling when your hand or foot falls asleep (a condition known as paresthesia) sure is aggravating. You can wake your hand up in under a minute, however, just by rocking your head side to side.

Always start from the thread spool pin, install your thread spool to the spool pin & put on the spool holder, pull end of thread to go thru the top thread guide then down to the tension disc(follow the arrow pointer if there is),up to the thread take up lever arm from left to right and down to the needle thru the needle clam guide(just below its needle clam screw)then enter the needle eye from front to back. Turn your hand wheel towards you to bring needle bar down into the bobbin case, keep turning till needle comes fully up, pull out your top thread end & this should bring up the bobbin thread then you be ready to sew.

Depends on the model, for detail but basically: Ensure the takeup arm / needle is at the top of its motion - with electronic models this is easiest done just by 'blipping' the foot controller and the needle will automatically return to top. Put your spool of thread on the spool pin. On older models with the vertical spool pins ALWAYS use a felt pad underneath to prevent the spool spinning when the thread is drawn off. On later models with a horizontal spool pin, hold the spool in place with the correct size retainer, with the larger diameter facing away from the spool. Make sure the foot is up (this is important). Draw thread off the spool and route it through the pre-tensioner on the back of the machine, then through the slot until it passes through the tension discs next to the tension control. The thread is then brought down the right-hand-side of the takeup arm cover, and pulled-up the left-hand side (it should be pulled into the check spring at the bottom, automatically. Pass the thread around the right-hand-side of the takeup arm and then the left-hand-side so that the thread is left running through the takeup arm. Drop the presser foot. Route the thread behind the lower thread guide at the bottom of the takeup arm cover and then through the thread guide at the bottom of the needle bar, just above where the screw that retains the needle is situated. The thread guide might be a simple loop of wire or a clip on the botom of the needle bar. Thread the thread through the eye of the needle either manually or using the needle threader, if fitted and off you go. It's important to have the foot raised when routing the thread through the upper tension discs to make sure the thread sits properly within the discs rather than just going over the top of them. Raising the foot holds the tension discs open.

Presser foot up, takeup lever at the top, thread on the top spool pin, take the thread to the left and over the top guide, straight down the right hand side of the tension and go round it making sure the thread goes between the discs, up the left hand side to the takeup lever, thread the takeup lever right to left, take the thread all the way down to the needle going through any guides on the way, thread the needle left to right, make sure the flat side of the needle is facing right.

You need two thread sources. This can be two spools or one spool and a bobbin on the spool pin.

Make sure the presser foot and needle plate openings are wide enough to accommodate the passing of the needles.

Lift the presser foot and beginning with the thread source to the far right, thread as usual through the right needle, then the left needle.

Make sure to use a straight stitch and you may have to loosen the tension a bit (test).

Hand walk the needles down and back up to catch the bobbin thread. Take all three threads under the presser foot and to the back of the machine.

Cotton omn the reel pin, take the thread from the right to the left and through the top cotton guide above the takeup lever, make sure the takeup lever is at the top and make sure the presser foot is up, take the thread down the right hand side, round the tension unit and back up the left hand side to the takeup lever, right to left through the takeup lever and then follow the guides all the way down to the needle and thread front to back, flat side of the needle must face back.
when you put the bobbin in, bobbin in your left hand and the thread must feed from the bottom of the bobbin, drop the bobbin, through the groove and lay the thread to the back.

From the reel pin take the thread to the left and over the top thread guide above the takeup lever, make sure the takeup lever is up and and make sure the presser foot is up, take the thread straight down and round the right hand side of the tension unit and back up the left hand side to the takeup lever, thread the takeup lever right to left and take the thread down any guides to the needle, if the bobbin case goes in the front thread the needle front to back, if the bobbin case goes in the side thread the needle left to right.

1. Push in indent (illustration 1) on hand wheel disc. This will stop the needle from moving.
2. Place spool of thread on spool pin.
3. Slide spool pin holder/cap (illustration 2) firmly over rim of spool to prevent thread from tangling.

3. Slide spool pin holder/cap (illustration 2) firmly over rim of spool to prevent thread from tangling.

4. Lead thread passing it first through the lower slot of the thread guide. Next through the upper slot, leading the thread to the right and around (illustration 3).
5. Wind thread clockwise around front of bobbin winder tension disc (illustration 4).
7. Pass thread end, from inside, through small hole in rim of bobbin.
8. Holding thread end, step on speed controller to run machine until desired amount of thread is wound. (Winding stops automatically once bobbin is full.)
9. Cut thread; push bobbin to the left and remove it from bobbin winder pin.
10. Trim thread end from top of bobbin.
11. Press the bobbin winding indent on hand wheel to its original position. If necessary, turn hand wheel to engage needle movement.
