get some scrap lumber laying around, even some pallets (most of the time you can get them free), just some cheap wood to start, don't run out and pay $5.00bdft for walnut to mess around with. I got some pallets from a neighbor, took out the nails,staples and got some decent oak planks and made picture frames. cheap,easy, and very helpful in learning your equipment and joining. welcome aboard to the forum. if you can't find the answer here, there aint one.lol as mentioned, post a pic of some thing you want to build and you'll get plenty of responses to help ya out. good luck and stay safe, dt.
Like BernieL mentioned keep those scraps and end cuts, before you put your nice pieces across the router, stick a scrap piece in there. that way you'll know if it's what ya want.
