Nearly all households have a pair of binoculars of some sort, and that's by far the easiest way. Even when there's no eclipse on schedule, you can always be on the lookout for sunspots.
ALREADY STATED ABOVE, BUT I'D BETTER REITERATE: NEVER LOOK THROUGH THE BINOCULARS AT THE SUN, NOR DIRECTLY AT THE SUN WITHOUT PROTECTION (ORDINARY SUNGLASSES, FILM NEGATIVES, ETC., ARE NO GOOD FOR THIS).
Anyway, back to the bins. Put a cap on one lens, you only need one half. Prop up a piece of white card or paper square-on to the binoculars and in their shadow a few feet away (keep your head well away from the binoculars' shadow)! Gently move the binoculars about until the sun's image (which may be blurred) pops through on to the card. Then, holding the bins as steady as you can with one hand, try to get a focus using the other hand. Once you've managed it and mastered the knack, you'll be amazed at the result.
This is not meant to be a 'professional' technique of course, but quite good enough for most people.
Oh and another thing. Use a pair of old, cheapo binoculars for this: certainly not ones with fancy electronics or image-stabilisation or anything like that - you'll wreck them!
