Hi Harriet
No worries =) LO = Layout for short and SB = Scrapbook
Most of the papers sold are 12" x 12" in size, most of the time, when matched, you might not use up the entire 12 x 12 pieces. Your darling daughter is really precious and creative!! It's so amazing how innovative children are!
Hahaha, unlike us adults or rather specifically myself, I rather work hard and earn the extra $$ to spend on this hobby of mine =P But nonetheless, we're all in for the beautiful things to touch and to hold.
Hope you'll have fun with your darling daughter too =) Oh, Crayola does sell some acid free glitter glue and markers for SB. Do keep a lookout for them, especially when Tangs or Robinsons having sale, you might get 20% off them too and they are not as expensive =)
