Hemstitching by machine

[satsumasalad.livejournal.com]

Hi, a quick question, I hope this isn't off topic, but the members here are bound to be the ones who know

I was casually browsing eBay today looking at hemstitched tablecloths, pillowcases and the like, and came across this item - a hemstitching fork for a sewing machine

Now I confess I have not used my sewing machine in many a long year but I'm pretty sure I have one of these in my box of attachments. If I could make my own hemstitched blanks for tatting onto, well....well words fail me.

Has anyone done this, is it straightforward, is it - how can I say - good enough?

Thanks for any replies
