Thank you for your help and the hints about using yellow! I've been reading reviews on some marking items and it seems the triangular pieces of chalk I was originally looking at are very prone to breaking, often arriving in several places. I've been using a mechanical lead pencil and the main problem I've been having is that I have to bear down hard and that "pushes" the fabric somewhat, making things uneven. I'm trying to avoid this, hoping to find something that only requires a light touch. I've put the clover 4712 and dritz 7751 in my amazon shopping cart. Oh my, when I put the dritz in the cost was about $20.00, it just jumped to almost $40!!! That one might be out!
Edited to add, price of the dritz is back down to about $13. I was going by the above links which are for Amazon Canada, I'm in the US.
