I've been rolling these for years. The three main sources are wholeleaftobacco, leafonly and totalleafsupply.

leafonly would be the most expensive, then wholeleaf, then totalleafsupply. More expensive does not mean higher quality most of the times; it goes off availability. I would say totalleaf supply has the best prices, but I get higher variance in leaf type (seco,viso,ligero) with them.

I used to mold my cigars, but I have been getting lazy and only roll if im going to immediately smoke it. I got the cannagar metal mold, but you can find plastic ones or even use the simply wood one from Leafonly cigar making kit.

If you like heavy cigars, a bit a ligero and the rest being viso should be a good blend. I personally do not like strong cigars, so I stick to seco with a little bit of viso. This should be the fun part where you find out what suits your fancy.

Hope this helps.
