Don't breathe the dust if you are cutting or sanding it, as it is carcinogenic. Same applies if you burning any waste MDF.

@Leathercraft Masterclass Hi Phil, That is exactly what I was looking for. Although I was aware of HDR in photography, I was lost with it's meaning on a stamp, so thanks for bringing me up to speed.

How much are the Metalic Elephant presses? I followed the link, but there are no prices. I am not sure what HDR is, but I orddered a large alphabet stam and a couple of makers marks from Hex N Hit a couple of years ago. I like using the stamps and found the people good to deal with. I cut down on charges and postage by getting them to courier them to my hotel when I was in Bangkok on holiday.

@Leathercraft Masterclass I was tempted to by a set of the round dent irons for a project I am going to start soon. I am going to make a US style mail bag which will be stitched inside out. My thought were that my normal angled prick holes might show at the seam when the bag is turned the right way out. Would I be right in saying that a straighter stitch would work better in this instance, and if so which irons would you recommend?
