I work in 8 1/2 x 11 size and started with 1 page and worked my way up from there. I put them into the page protectors and now have about 12 albums(binders which go on sale at back to school time). Many people do the 12 x 12 size but I like the smaller size I use.
Depending on the size you choose to start, get or make your embellishments( I like rubber stamp designs). You will be on your way to scrap booking creativity and more picture taking
I watch at garage sales in the Summer time to get cool supplies and find tons of them and cardstock too!
Welcome! I am sure you will find many ideas in the Gallery too to inspire your new hobby
Have Fun and people are always here to answer questions you might have along the way! Just remember to use scrap safe papers and cardstock and your pictures will last for many many years for everybody to look at!
