I bought mine on Internet from China. I didnt know the diameter of the pronges but I can tell you this: the diamond chisels I got from China I always fail with, they dont cut through very well and the handle is not thick so hammering it causes the chisel to go through at an angle. If you are using round head chisels which ones do you use and if you by any chance use diamond chisels which one do you recommend? 

You can get good results with any of them. 

Many people have strong opinions about what is best or right, but they are mostly opinions.  Some looks are liked by more people, and some approaches can look more finished or consistent to a customer.  But some crooked stitches or uneven stitch spacing does not really affect anything except looks and resale value.  This is a cardholder, not a parachute (an example where certain details do matter).

In order for your holes to turn out right, there are some things you can do.  Rotate your project so you are looking along the line of stitching.  Take your punch and hold it straight up and down.  Pick up your mallet.  BEFORE YOU HIT THE CHISEL, rest the head of the mallet on the top of the chisel.  THEN, raise or lower the mallet's handle until it is going straight out, horizontal.  NOW, raise and lower your hand/arm to hit the chisel, and when you swing down try to retrace your steps so the mallet goes right back to where it was.  

If your mallet hits with the handle higher or lower than horizontal, or if your chisel is not straight up and down, then the chisel will exit higher or lower than you want it.  The thicker the leather, the more precisely you must hold the chisel.

When it comes to stitch spacing, ideally this would be figured out ahead of time on a pattern/template.  If you work straight onto the leather, as many of us do, we run the risk of more errors and also run the risk of having to 'bluff' a bit more with our stitch spacing.

it's all about math 8 spi for example one stitch = 1/8th inch so your stitching has to be measured in 1/8th inches. measure your stitch line then do the math if it doesn't come out correct then use a different spi that fits or lengthen or shorten your line. On this wallet it would be of little consequence to make it a few mm bigger or smaller to make your holes, chisels or punches come out even. That's what mock ups are about and patterns are for, getting the small stuff correct so it all goes together easily and quickly every time, doesn't matter what is making the holes.

I also noticed on your wallet your holes on the sides are punched with your line  on the sides of the holes on the bottom the line is in the center of the holes that little bit of difference will throw you off by half a stitch as will the rounded corner your corner holes are out of line so the stitch length will be affected

Spyros is making a case for his own opinion and there's nothing wrong with that but I had to smile when he listed all the good bits about hole punches and then said "But you don't wanna do that do you".

I know, this probably sounded a bit confusing, sorry :)

I'm not hand stitching because I can't afford a sewing machine, I can, I just think there is additional value in hand stitching.  And part of that value is the look, so if I'm going through the trouble of doing it I want the full return on my investment, which includes the visual element.  I just think round chisels kind of hide it.

Having said that, I'm still very new to all this and I'm still changing opinions.

When you reach a corner with the diamond chisel how do you place the chisel? for example I have a card holder I am doing right now. The holes begin from straight up to down and when I am going from the top line to the bottom I'm not sure how to hold the chisel here? see attached image

I use a single-tooth chisel to make one hole on the apex of the corner. I then work from the corners to the centre of the side or bottom, making a row of holes alternately, so that the last few holes are at about the centre of the side

At the moment I cannot see your picture. It might have somat to do with the present site problems

Hi,

 

Maybe there is a problem with the website. My question is if you have a corner and the corner radius is not so much and you intend to stitch with 4 mm spacing. When the template is finished you notice that on the bottom left and right corners of the card holder you don't have a stitching hole, you have one on the line going straight up and a hole on the bottom going horizontally, meaning there is no hole to connect the vertical and horizontal stitching line. After punching the holes from top to bottom corner do you rotate your project 90 degrees and then punch holes on the bottom from top to down? I feel like the connection of stitching is important here, I don't want the stitching to look unnatural between side and bottom of my card holder, maybe it is recommended to use a stitching hole at the corner between the two lines to make it look more consistent?

Fred has it right. Work from each corner alternatively and work out any anomalies in the center There's absolutely no reason why you couldn't use a small hole in the corner if it suits your project.In fact I've seen lots of projects where a diamond slant look off in the corner.I suppose the radius of the corner comes into it as well. With spacing, on quite a lot of projects you can actually alter the size slightly to suit whatever chisel/punch you want to use. You don't think Nigel Armitages or Ian Atkinsons spacing works out perfectly every time is a coincidence do you?

The thing I haven't seen mentioned re:  slits versus holes is curves. It's one thing to have this debate about flat surfaces but is there a difference when working with 3D curves? I've only used holes when doing Dieselpunk.Ro patterns which have all sorts of curves sometimes and it's fascinating to watch the thread pulling those curves together. I guess it's designer preference whether they use circles/dots/crosses but on tight radii the comments above will come into the "look".

Nigel Armitage's great trick on Youtube is to use a scratch awl and mallet to make one round hole right where the two lines cross.  You sew it the same but the result is tidier.

When i don't do that, I straddle the lines evenly, so each of the two prongs are the same distance from the corner, leaving one stitch right about 45 degrees betweem the two lines.  I don't have a reason why I pick one approach over another on a specific project.

Thank you, I will try this.
