I use the (bought) MYLAR templates with the hole punched out in the middle... then had some extra template plastic (that I bought at JoAnn's) that is heat-resistant with my iron ... and made my own! much less expen$ive.
HINTS:
* the larger the hexagon, the quicker it will go.
* if you keep these by your TV chair, you can whip out several in an evening;
* likewise keep a qt. zip-lock baggie with them and a needle and some thread in your purse for waiting at doctor's offices, appt's, etc.
* pin, trace, cut, sew....Do these in batches; put aside; start again... it breaks up the monotony!
* I've also put together one "flower" and then appliqued it on to a square background (tho' it could be a very large hexagon) ... that really makes for a larger quilt top, with lots less work.
GOOD LUCK with yours. I'm sure whenever it is finished it will be lovely and you know you did it ALL by hand!
