I'd recommend starting with weapons you use most like AK and M4. No point buying a fancy AWP skin if you're terrible at sniping! Focus on your main weapons first then expand later

Smart approach from both of you! When I started collecting, I made the mistake of buying skins for weapons I rarely used just because they looked cool. Now I focus on my actual playstyle and main weapons. What really helped was understanding different skin categories and their values through detailed guides at https://dmarket.com/cs2-wiki/ before making purchases. This way you can plan your collection strategically rather than just impulse buying. Start with your most-used weapons, learn about float values and rarity levels, then gradually expand to secondary weapons. Having a plan makes collecting way more satisfying and cost-effective than random purchases
